They are also known as 3-D (3-Dimensional) shapes. The main difference between flat shapes and solid shapes is that the flat shapes or plane shapes only have two dimensions and solid shapes have 3 dimensions.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">These solid shapes occupy some space and are found in our day-to-day life.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">We can feel, touch, and use them.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Definition of Solid Geometry: The study of 3-dimensional objects, their volume, surface area, properties is called the \u2018solid geometry\u2019.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">The geometrical figures are classified based on the dimensions as follows:<\/p>\n\n\n\n<ul class=\"eplus-wrapper wp-block-list\">\n<li class=\" eplus-wrapper\"><strong>Zero-dimensional shape<\/strong> \u2013 A zero-dimensional shape is the shape that has no length, no breadth and no height. For example: a point<strong>.<\/strong><\/li>\n\n\n\n<li class=\" eplus-wrapper\"><strong>One-dimensional shape<\/strong> \u2013 A one-dimensional shape has only one dimension. For example, a line has a length as its dimension.<\/li>\n\n\n\n<li class=\" eplus-wrapper\"><strong>Two-dimensional shapes<\/strong> \u2013 A shape that has length and breadth as two dimensions. For example: square, triangle, rectangle, parallelogram, trapezoid, rhombus, quadrilateral, polygon, circle, etc.<\/li>\n\n\n\n<li class=\" eplus-wrapper\"><strong>Three-dimensional shapes <\/strong>\u2013 A shape with three dimensions, i.e., length, breadth and height. For example: cube, cuboid, cone, cylinder, sphere, pyramid, prism, etc.<\/li>\n\n\n\n<li class=\" eplus-wrapper\"><strong>Higher-dimensional shapes<\/strong> \u2013 There are a few shapes expressed in dimensions higher than 3, but we usually do not study them in middle-level mathematics.<\/li>\n<\/ul>\n\n\n\n<div id=\"recommended-games-container-id\" class=\"recommended-games-container\"><h4 class=\"recommended-games-container-headline\">Recommended Games<\/h4><div class=\"recommended-games-container-slides\"><div class=\"game-card-container-outer\">\r\n\t<a href=\"https:\/\/www.splashlearn.com\/s\/math-games\/compare-flats-and-solids\" data-vars-ga-category=\"splashlearn_vocab\" data-vars-ga-action=\"games_recommendations\" data-vars-ga-label=\"post_widget\">\r\n\t\t<div class=\"game-card-container-inner-block\">\r\n\t\t\t<img decoding=\"async\" class=\"game-card-container-inner-img\" src=\"https:\/\/cdn.splashmath.com\/curriculum_uploads\/images\/playables\/geometry_compare_flats_solids_pt.png\" alt=\"Compare Flats and Solids Game\">\r\n\t\t<\/div>\r\n\t\r\n\t\t<div class=\"game-card-container-inner\">\r\n\t\t\t<div class=\"game-card-container-inner-name\">Compare Flats and Solids Game<\/div>\r\n\t\t\t<span class=\"game-card-container-inner-cta\">Play<\/span>\r\n\t\t<\/div>\r\n\t<\/a>\r\n<\/div><div class=\"game-card-container-outer\">\r\n\t<a href=\"https:\/\/www.splashlearn.com\/s\/math-games\/sort-flat-and-solid-shapes\" data-vars-ga-category=\"splashlearn_vocab\" data-vars-ga-action=\"games_recommendations\" data-vars-ga-label=\"post_widget\">\r\n\t\t<div class=\"game-card-container-inner-block\">\r\n\t\t\t<img decoding=\"async\" class=\"game-card-container-inner-img\" src=\"https:\/\/cdn.splashmath.com\/curriculum_uploads\/images\/playables\/geometry_flats_solids_pt.png\" alt=\"Sort Flat and Solid Shapes Game\">\r\n\t\t<\/div>\r\n\t\r\n\t\t<div class=\"game-card-container-inner\">\r\n\t\t\t<div class=\"game-card-container-inner-name\">Sort Flat and Solid Shapes Game<\/div>\r\n\t\t\t<span class=\"game-card-container-inner-cta\">Play<\/span>\r\n\t\t<\/div>\r\n\t<\/a>\r\n<\/div><\/div><p class=\"recommended-games-container-desc\"><a href=\"https:\/\/www.splashlearn.com\/games\">More Games<\/a><\/p><button class=\"scroll-right-arrow\"><\/button><\/div><script type=\"text\/javascript\">\n        document.addEventListener(\"DOMContentLoaded\", function() {\n            const container = document.querySelector(\"#recommended-games-container-id\");\n            const slidesContainer = container.querySelector(\".recommended-games-container-slides\");\n            const cards = slidesContainer.querySelectorAll(\".game-card-container-outer\");\n            const scrollRightArrow = container.querySelector(\".scroll-right-arrow\");\n\n            function adjustContainerStyles() {\n                const numCards = cards.length;\n\n                if (numCards === 1) {\n                    container.style.maxWidth = \"30%\";\n                    container.style.textAlign = \"center\";\n                } else if (numCards === 2) {\n                    container.style.maxWidth = \"50%\";\n                    container.style.textAlign = \"center\";\n                } else if (numCards === 3) {\n                    container.style.maxWidth = \"75%\";\n                    container.style.textAlign = \"center\";\n                } else {\n                    container.style.maxWidth = \"\";\n                    container.style.textAlign = \"\";\n                }\n            }\n\n            function checkScrollPosition() {\n                const maxScrollLeft = slidesContainer.scrollWidth - slidesContainer.clientWidth;\n                if ((slidesContainer.scrollLeft + 10) >= maxScrollLeft) {\n                    scrollRightArrow.style.display = \"none\";

The rectangle is a plane figure, whereas the cuboid looks more like a real solid figure.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Solid shapes are three-dimensional (3D) geometric shapes that occupy some space and have length, breadth, and height. Solid shapes are classified into various categories. Some of the shapes have curved surfaces; some of them are in the shape of pyramids or prisms.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">The following image shows a cuboid or a rectangular prism with its 3 dimensions. The lower surface on which a solid object stands is called its base. The given cuboid has a rectangular base.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"531\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/solid-shape-2.png\" alt=\"3 dimensions of a solid shape cuboid \" class=\"wp-image-23420\" title=\"3 dimensions of a solid shape cuboid \" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/solid-shape-2.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/02\/solid-shape-2-300x257.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\" eplus-wrapper\">You will find multiple objects that fit the solid shape criteria if you look around.
