6.33 x 4.5 is only 28.485 sq. ft. 4 x 8 is 32 sq. ft. So one sheet will do if you cut it correctly.
If offcuts are used then 1 will be sufficient.
The sheet of plywood will cover 32 square feet. The area you have is only 28.485 square feet. One sheet is all you need.
how many boxes of wood flooring would i need if there are 19.72 sq feet in a box to cover 640 sq feet of an area?
Approximately 73 square feet.
1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
You will need 3.5 square yards of material to cover 32 square feet.
You will need at least 32 square yards of carpet to cover that area.
Depends on the size of the sheets of plywood.
