How many sheets of 4' x 8' x 1/2" drywall are required for a room sized 10' x 15' with an 8-foot ceiling?

To determine the number of sheets of drywall required for a room sized 10 feet by 15 feet with an 8-foot ceiling, the first step is to calculate the total wall area that needs to be covered.

1. Calculate the perimeter of the room:

• The perimeter is calculated as follows:

• Perimeter = 2 * (length + width) = 2 * (10 + 15) = 2 * 25 = 50 feet.

2. Calculate the total wall area:

• The walls' area can be found by multiplying the perimeter by the height of the walls (ceiling height).

• Total wall area = Perimeter * Height = 50 feet * 8 feet = 400 square feet.

3. Calculate the area of one sheet of drywall:

• A standard sheet of drywall measures 4 feet by 8 feet, so the area of one sheet is:

• Area of one sheet = Length * Width = 4 feet * 8 feet = 32 square feet.

4. Calculate the number of sheets required:

• To find the total number of sheets needed, divide the total wall area by the area of
