Create a cube using string, and the volume of the cube at its largest is 3375 cubic centimeters (cm3). Find the length of the string.
3375 1/3 [OP_POW] 12 [OP_MUL]
var_a = 3375
var_b = 0.3333333333333333
var_c = var_a ** var_b
var_d = 12
var_e = var_c * var_d
print(int(eval('{:.2f}'.format(round(var_e+1e-10,2)))))
