Polly saves her coins in a cube-shaped coin bank. Her coin bank is 7 inches wide and 7 inches tall. What is the volume of Polly's coin bank?

Answer 1

The volume of a cube is found by multiplying the length, width, and height together.

In this case, since the coin bank is cube-shaped, the length is also 7 inches.

So the volume = 7 inches x 7 inches x 7 inches

Simplifying, we get:

V = 343 cubic inches

Therefore, the volume of Polly's coin bank is 343 cubic inches.
