Front

How many faces does a rectangular prism have?

Back

A rectangular prism has 6 faces.

Front

What is the difference between a face and an edge?

Back

A face is a flat surface of a three-dimensional shape, while an edge is the line segment where two faces meet.

Front

What is the formula for the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.
