A large square was made by attaching several squares with a side length of 6 centimeters (cm). Find how much the square's area has increased if the length and width of the large square are three times their original length.
6 3 [OP_MUL] 2 [OP_POW] 6 2 [OP_POW] [OP_SUB]
var_a = 6
var_b = 3
var_c = var_a * var_b
var_d = 2
var_e = var_c ** var_d
var_f = 6
var_g = 2
var_h = var_f ** var_g
var_i = var_e - var_h
print(int(var_i))
