You built a cuboid-shaped pond with a length of 18 meters (m), a width of 10 meters (m), and a height of 2 meters (m). If you are going to paint the inner side of the pond, how many square meters (㎡) of the pond could be painted?
18 10 [OP_MUL] 10 2 [OP_MUL] 2 18 [OP_MUL] [OP_ADD] 2 [OP_MUL] [OP_ADD]
var_a = 18
var_b = 10
var_c = var_a * var_b
var_d = 10
var_e = 2
var_f = var_d * var_e
var_g = 2
var_h = 18
var_i = var_g * var_h
var_j = var_f + var_i
var_k = 2
var_l = var_j * var_k
var_m = var_c + var_l
print(int(var_m))
