You can put this solution on YOUR website!
let the side of the cube be a
since a=4in+=%281%2F3%29+ft, we will use ft
if volume is V=a%2Aa%2Aa=a%5E3, ... plug in a

V=%281%2F3%29+ft%2A%281%2F3%29+ft%2A%281%2F3%29+ft=%281%2F27%29+ft%5E3
It would take 27 of these small cubes to build a cube of 1cu_ft.
