Volume of the block is 6*12*15=1080
HCF is among those three measures is 3 (find the greatest common division) to find the small cube
Volume of this cube is 3^3=27
The number of cubes possible is the largest or total volume by the small volume
1080/27=40

Why can't you use a cube with a volume of 1?
