A rectangular prism with a volume of 252 cubic centimeters (cm3) was made by stacking 36 stacking blocks with a volume of 1 cubic centimeter (cm3). How many layers are there in this cuboid's stacking blocks?
252 36 1 [OP_MUL] [OP_DIV]
var_a = 252
var_b = 36
var_c = 1
var_d = var_b * var_c
var_e = var_a / var_d
print(int(var_e))
