Question

A right rectangular prism is packed with cubes of side length fraction 1 over 5 inch. If the prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height, what is the volume of the prism?

Answer 1

3.6 in³

Explanation:

If each cube is 1/5 inch:

15 cubes along the length = 15÷5 = 3 inches

5 cubes along the height = 5÷5 = 1 inch

6 cubes along the width = 6÷5 = 1.2 inches (1 and 1/5)

V=lwh=3*1*1.2= 3.6 in³
