Using all of the wire, not overlapping, a regular pentagon with sides of 16 centimeters (cm) was made. How many centimeters (cm) should each side be to make the largest regular octagon with this wire?
16 5 [OP_MUL] 8 [OP_DIV]
var_a = 16
var_b = 5
var_c = var_a * var_b
var_d = 8
var_e = var_c / var_d
print(int(var_e))
