A necklace is made by attaching 16 pieces of colored paper each 10.4 centimeters (cm) in length, overlapping each other by 3.5 centimeters (cm). How many centimeters (cm) is the total length of the necklace made of colored paper?
10.4 16 [OP_MUL] 3.5 16 [OP_MUL] [OP_SUB]
var_a = 10.4
var_b = 16
var_c = var_a * var_b
var_d = 3.5
var_e = 16
var_f = var_d * var_e
var_g = var_c - var_f
print('{:.2f}'.format(round(var_g+1e-10,2)))
