The right rectangular prism is filled with cubes that have a side length of 1/8 foot.
How many cubes does it take to fill the prism? (Look at the photo please!!)

Find the volume of the rectangular prism and divide by the volume of the cube.

Volume of cube = side measure ^ 3
Cube = (1/8)^3 = 1/512

Volume of prism = l x w x h
Prism = (1/4)(1/2)(3/8) = 3/64

3/64 / 1/512
3/64 x 512/1
3 x 512 / 64
1536 / 64
