There is a regular octagonal prism whose sum of the lengths of its edges is 240 centimeters (cm). If the height of this prism is 12 centimeters (cm), what is the length of one side of the base?
240 12 8 [OP_MUL] [OP_SUB] 8 [OP_DIV] 2 [OP_DIV]
var_a = 240
var_b = 12
var_c = 8
var_d = var_b * var_c
var_e = var_a - var_d
var_f = 8
var_g = var_e / var_f
var_h = 2
var_i = var_g / var_h
print(int(var_i))
