Sam is building a new deck. His decking material is sold by the square foot. At a cost of $3.90 per square foot, how much will it cost Sam to build a deck that is 18 feet by 14 feet?

notamathgenius · Answer

Ok so you know what the cost, width, and height are so what do you need to do first?

anonymous · Answer

You have to find the area first so 18 times 14 =252

notamathgenius · Answer

Ok now per sq. ft. You need to divide what by what?

anonymous · Answer

I mean i multiplied 252 by 3.90 and got one of the answers on the quiz. Which is 982.8

notamathgenius · Answer

So if you are correct which you are you should get 983 (needs to be rounded you want more not less) sq.ft of wood
