Find the volume of a cube with side length of 7 in.

A: 147 in³ B: 49 in³

C:215 in³ D: 343 in³

Answer: 343 in³

Explanation: In this problem, we're asked to find the volume of a cube.

It's important to understand that a cube is a type of rectangular prism and the formula for the volume of a rectangular prism is shown below.

Volume = length * width * height

In a cube however, the length, width, and height are all the same. So we can use the formula side * side * side instead.

So the formula for the volume of a cube is side * side * side or s³.

So to find the volume of the given cube, since each side has a length of 7 inches, we can plug this information into the formula to get (7 in.) ³ or (7 in.) (7 in.) (7 in).

7 x 7 is 49 and 49 x 7 is 343.

So we have 343 in³.

So the volume of the given cube is 343 in³.
