Question

What's the combined volume?

2 inches wide and 2 inches tall cube

6 inches wide and long, 2 inches in height rectangular prism

Answer 1

The volume of the cube is calculated by V = s^3, where s is the length of one side of the cube. So for the 2 inch cube it would be: V = 2^3 = 8 cubic inches.

The volume of the rectangular prism is calculated by V = lwh, where l is the length, w is the width, and h is the height. So for the 6x6x2 rectangular prism it would be: V = 6 x 6 x 2 = 72 cubic inches.

Adding the two volumes together we get:

8 cubic inches (cube) + 72 cubic inches (rectangular prism) = 80 cubic inches

Therefore, the combined volume of the two shapes is 80 cubic inches.
