What is the Right Rectangular Prism?
A right rectangular prism is a three-dimensional object with 6 faces, 12 edges, and 8 vertices.
In a right rectangular prism:
- the angles between the base and sides are right angles.
- all the 6 faces are rectangles.
This prism is also called a cuboid and each corner of the prism is a right angle. Each base and top of a rectangular prism is congruent; that is; exactly of the same shape and size.
Real-life examples of a Right Rectangular Prism:
Right rectangular prisms or cuboids are all around us. A few examples are books, boxes, buildings, bricks, boards, doors, containers, cabinets, mobiles, and laptops.
Non-examples of a right rectangular prism:
- This shape is a prism but its top and base do not have right angles in the shape. This is not a right rectangular prism.
- This shape is not a prism. Neither it has rectangles in top and bottom nor there are any right angles in them. This is also not a right rectangular prism.
Net of a right rectangular prism:
The net of a 3D object shows the faces of that object when it is opened flat. We can form a right rectangular prism using its net as shown below as each face of the net is a rectangle that has right angles to it.
| Fun Facts 1. Rectangular prisms can have more than one net. 2. A cube is also a right rectangular prism with all its sides of equal length. 3. If the bases of a right-angle prism are square, then it is called a square prism. |
