How many sheets of 4x8 plywood do you need to cover a 16x18floor?

Answer 1

A 4x8 sheet of plywood covers 32 sq feet. You need to cover 16x18 which equals 288 sq feet. Divide 288 by 32 and you will need 9 pieces of plywood.

However, don't forget to add for waste. Usually 10-15% unless your room is without obstructions, walls, etc. For this job, you may need at least (1) additional sheet to complete the project.
