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

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

• A. 16 sheets
• B. 18 sheets
• C. 20 sheets
• D. 22 sheets

Answer: (B)

To determine how many sheets of drywall are needed for a room that is 10 feet by 15 feet with an 8-foot ceiling, it's important to first calculate the total square footage of the walls and then divide that by the square footage of each sheet of drywall. 1. **Calculate the perimeter of the room**: - The perimeter of a rectangular room can be calculated using the formula: Perimeter = 2(length + width) = 2(10 ft + 15 ft) = 2(25 ft) = 50 ft. 2. **Calculate the total wall area**: - The area of the walls is given by multiplying the perimeter by the height of the walls: Wall Area = Perimeter x Height = 50 ft x 8 ft = 400 sq ft. 3. **Calculate the area of each sheet of drywall**: - Each sheet of drywall measures 4 feet by 8 feet, so the area of one sheet is: Area of one sheet = 4 ft x 8 ft = 32 sq ft. 4. **Find the number of sheets needed**: - To find the total number of

To determine how many sheets of drywall are needed for a room that is 10 feet by 15 feet with an 8-foot ceiling, it's important to first calculate the total square footage of the walls and then divide that by the square footage of each sheet of drywall.

1. Calculate the perimeter of the room:

• The perimeter of a rectangular room can be calculated using the formula:

Perimeter = 2(length + width)

= 2(10 ft + 15 ft)

= 2(25 ft)

= 50 ft.

2. Calculate the total wall area:

• The area of the walls is given by multiplying the perimeter by the height of the walls:

Wall Area = Perimeter x Height

= 50 ft x 8 ft

= 400 sq ft.

3. Calculate the area of each sheet of drywall:

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

Area of one sheet = 4 ft x 8 ft = 32 sq ft.

4. Find the number of sheets needed:

• To find the total number of
