polynomial functions…is what i did right?
Jimmie is building a sandbox that is 12 times as wide as it is deep, and 1m longer than it is wide. It holds 3m^3 of sand when full. The wood cost $24/m^2. How much will the wood cost Jimmie? (btw, there is no top or bottom, just the sides when calculating for the area!!) (that the question…now i got the answer $84….is that right??? if so, can someone confirm that? if not , how would you get the correct answer….) ?? thanks!!
