There are regular hexagonal prisms and square pyramids with the same edges. The sum of the lengths of all the edges of the hexagonal prism is 81 centimeters (cm). What is the sum of the lengths of all the edges of the pyramid in centimeters (cm)?
81 6 3 [OP_MUL] [OP_DIV] 4 2 [OP_MUL] [OP_MUL]
var_a = 81
var_b = 6
var_c = 3
var_d = var_b * var_c
var_e = var_a / var_d
var_f = 4
var_g = 2
var_h = var_f * var_g
var_i = var_e * var_h
print(int(var_i))
