Ginny has a sheet of plywood that is 4 feet by 8 feet. she wants to saw the plywood into pieces 1 foot high and 2 feet long for signs. how many signs can she make with the sheet of plywood?

To solve this problem you first get the area of the plywood that is  4' by 8'
4 * 8 = 32

Next you get the area of the pieces, which is 1' by 2'
1 * 2 = 2

Next you see how many pieces will go into the whole plywood.

32 / 2 = 16
So she can make 16 signs.

In the real world this would not be possible because you have to take in the fact the saw blade thickness which cuts the wood and takes a little bit of the wood away per cut but for Acadima this will suffice.
