Front

What is a cuboid?

Back

A cuboid is a box-shaped object with six flat faces, all angles are right angles, and all faces are rectangles.

Front

Why is a cuboid also called a rectangular prism?

Back

A cuboid is called a rectangular prism because it has the same cross-section along its length.

Front

Can you give examples of cuboids?

Back

Examples of cuboids include buildings, boxes, and containers.

Front

What does the term 'cuboid' mean?

Back

The term 'cuboid' comes from 'cube' and the suffix '-oid', meaning 'similar to or resembling a cube'.

Front

What is the formula for the surface area of a cuboid?

Back

The surface area is calculated using the formula: A = 2wl + 2lh + 2hw.

Front

How do you find the surface area of a cuboid with dimensions 4, 10, and 5?

Back

Using the formula: A = 2(4)(10) + 2(10)(5) + 2(5)(4) = 220.
