A rectangular prism with a volume of 10 cubic units is filled with cubes with side lengths of 1/2 unit.

How many 1/2 unit cubes does it take to fill the prism?

Answer 1

80 cubes

Explanation:

volume of one small cube = 1 /2 × 1 / 2 × 1 / 2

= 1 / 8cm^3

let x be the number of cubes needed

1 / 8 × x = 10

x = 10 × 8

x = 80 cubes
