a rectangular block 15 cm by 30 cm by 75 cm is cut into an exact number of equal cubes . find the least possible number of cubes ?
n0 = 15.0
n1 = 30.0
n2 = 75.0
t0 = 1000.0 * 3.0
t1 = n2 * 10.0
t2 = 2.0 * 3.0
t3 = 1000.0 * 360.0  # area of rectangle
t4 = t0 + t1
t5 = t3 / 10.0
t6 = t2 * 1000.0
t7 = t5 - t6
t8 = t4 + t7
t9 = t8 / 10.0
answer = t8 / t9
