How many full sheets of 4 x 8 plywood are needed for a rectangular subfloor that is 34' x 72'?

To determine how many full sheets of 4 x 8 plywood are required for a rectangular subfloor measuring 34 feet by 72 feet, you first calculate the total area of the subfloor and then the area of each plywood sheet.

The area of the subfloor can be calculated by multiplying its length by its width:

Area of the subfloor = 34 feet x 72 feet = 2,448 square feet.

Next, calculate the area of one sheet of plywood:

Area of one sheet of plywood = 4 feet x 8 feet = 32 square feet.

Now, to find out how many sheets of plywood are necessary, you divide the total area of the subfloor by the area of one sheet:

Number of sheets needed = Total area of the subfloor / Area of one sheet of plywood

Number of sheets needed = 2,448 square feet / 32 square feet = 76.5.

Since you cannot purchase half a sheet of plywood, you must round up to the next whole number, which is 77 sheets.

However, this calculation implies that the answer you provided (10 sheets) does not come from the context needed for the calculation of how many full sheets would be used.
