a rectangular block 12 cm by 20 cm by 36 cm is cut into an exact number of equal cubes . find the least possible number of cubes ?
"volume of the block = 12 * 20 * 36 = 8640 cm ^ 3 side of the largest cube = h . c . f of 12 , 20,36 = 4 cm volume of the cube = 4 * 4 * 4 = 64 cm ^ 3 number of cubes = 8640 / 64 = 135 answer is a"
