Question

Part 1
A box is in the shape of a cube. The box has edge lengths of 9 in. How many unit cubes are needed to fill the​ box?

Answer 1

To find the number of unit cubes needed to fill the box, we need to calculate the volume of the box first.

Since the box is in the shape of a cube, all three edges have the same length of 9 inches.

The volume of a cube is given by the formula V = s^3, where s is the length of one side.

Therefore, the volume of the box is V = 9^3 = 729 cubic inches.

Since each unit cube has a volume of 1 cubic inch, the number of unit cubes needed to fill the box is 729.
