There are 28 identical shelves in the warehouse. Each shelf has 6 spaces with the same number of books in it. If 19 books are on one shelf, what is a total number of books on the shelf in the warehouse?
28 6 [OP_MUL] 19 [OP_MUL]
var_a = 28
var_b = 6
var_c = var_a * var_b
var_d = 19
var_e = var_c * var_d
print(int(var_e))
