18 mm is a measure of the thickness of the plywood. It gives no information at all on the length or width of the ply, which is what is required to calculate a volume.
8x4=32. 14x14=196. 196/32=6.125. You can use a maximum of 6 bricks, which will only cover 192 of the 196 square units.

25 will cover it. I'd get 28.
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.

Area of a sheet of plywood = 4' x 8' = 32. 1700ft2/32ft2 = 53.125 54 sheets of 4' x 8' plywood would be needed to cover 1700ft2.
It depends on the size of the plywood sheets.

6 pieces of plywood will cover this area without a lot of piecing.
