a statue is being carved by a sculptor . the original piece of marble weighed 140 kg . in the first week 60 percent is cut away . in the second week 40 percent of the remainder is cut away . in the third week the statue is completed when 30 percent of the remainder is cut away . what is the weight of the final statue ?
a 24 kg 140 ã — 0.4 ã — 0.6 ã — 0.7 = 24 kg .
multiply(subtract(const_1, divide(30, const_100)), multiply(subtract(const_1, divide(40, const_100)), multiply(140, subtract(const_1, divide(60, const_100)))))
