a rectangular block 6 cm by 12 cm by 15 cm is cut into an exact number of equal cubes . find the least possible number of cubes ?
"volume of the block = 6 * 12 * 15 = 1080 cm ^ 3 side of the largest cube = h . c . f of 6 , 12,15 = 3 cm volume of the cube = 3 * 3 * 3 = 27 cm ^ 3 number of cubes = 1080 / 27 = 40 answer is c"
