A certain type of candle is packaged in boxes that measure 42 cm by 17 cm by 10 cm. The candle company that produced the above packaging has now designed shorter candles. A smaller box will be created by decreasing each dimension of the larger box by the same length. The volume of the smaller box will be at the most 2220 cm3 . What are the maximum dimensions of the smaller box? Solve this problem algebraically. Please use The Factor Theorem.
i am trying to solve this by (42-x)(17-x)(10-x) = 2220
pls let me know is this the right way.
