For a rectangular subfloor that measures 34' x 72', how many full sheets of 4 x 8 plywood are needed?

To determine how many full sheets of 4 x 8 plywood are needed for a rectangular subfloor measuring 34 feet by 72 feet, you first need to calculate the area of the subfloor. The area can be found using the formula for the area of a rectangle, which is length times width.

Calculating the area of the subfloor:

Area = Length × Width

Area = 34 feet × 72 feet

Area = 2448 square feet.

Now, calculate the area of a single sheet of plywood. A standard sheet of plywood measures 4 feet by 8 feet, so its area is:

Area of plywood sheet = 4 feet × 8 feet = 32 square feet.

Next, to find out how many sheets of plywood are required, divide the area of the subfloor by the area of one sheet of plywood:

Total sheets needed = Area of subfloor / Area of one sheet of plywood

Total sheets needed = 2448 square feet / 32 square feet = 76.5 sheets.

Since you can only use full sheets, you will round up to the next whole number, which is 77 sheets. This calculation leads to the conclusion that 77 full sheets of plywood are needed to
