Best Answer

Total area needed to cover: A = 10x12=120 area units

Area of one piece of plywood: A = 4x8 = 32 area units

You will have to divide the total area that needs to be covered with the area of on plywood board, to get how many plywood boards you can fit in the same area.

120/32 = 3,75

Answer: You will have to use 4 pieces of plywood, or more precisely 3 whole and 3 fourths of a plywood board.
