Question

A cartoon in the shape of a cube measuring 8 inches tall is filled with colored plastic cubes measuring 1 inch across each face. The cubes sell for 25cent each. How much would it cost to buy all of the cubes in the carton? Enter your answer in the box?

Answer 1

The entire package is a cube, so its volume is 8 x 8 x 8 = 512 in^3. Each small cube is 1 x 1 x 1 = 1 in^3. Therefore, there are 512 in^3 / 1 in^3 = 512 cubes, and since each cube is 25 cents, it would cost (512 cubes)($0.25) = $128 to buy all the cubes in the carton.
