4 x 10 is 40 square feet, so two would do it.
To calculate the amount of drywall needed for a 14 by 20 foot room with 9-foot walls and a ceiling, first determine the area of the walls and ceiling. The walls' total area is (2 \times (14 + 20) \times 9 = 612) square feet, and the ceiling area is (14 \times 20 = 280) square feet. Adding these together gives (612 + 280 = 892) square feet. Drywall typically comes in 4x8-foot sheets, so you would need about 28 sheets (since each sheet covers 32 square feet).
6-4'x8' sheets
Approx. 113 sheets
56 sq feet
Multiply the length of the ceiling (in feet) by the width of the ceiling (in feet). For example, if a ceiling is 4 ft by 6 feet, the area would be 24 sq ft.

To calculate the amount of drywall needed for a project, measure the height and width of the walls or ceilings to be covered. Multiply the height by the width to get the square footage. Subtract the area of any doors or windows. Divide the total square footage by the size of the drywall sheets (usually 4'x8') to determine how many sheets are needed.
About 94 sheets if 4x8.
To determine how many drywall sheets are needed to cover a 24x24 garage, first calculate the total wall area. Assuming an 8-foot ceiling, the total wall area is approximately 768 square feet (perimeter of the garage, 96 feet, multiplied by the height of 8 feet). Standard drywall sheets are 4x8 feet, covering 32 square feet each. Therefore, you would need about 24 sheets of drywall (768 square feet divided by 32 square feet per sheet), plus some extra for waste and cuts, so consider purchasing 26-28 sheets.
You can both estimate the total square feet of drywall, also known as gypsum board, you'll need and the number of sheets. ... Drywall needed = total area/sheet size. Multiply the length and height of one wall. ... Record the area. Repeat this process for all walls.
To calculate the amount of drywall needed for your project, measure the height and width of each wall in feet. Multiply the height by the width to get the square footage of each wall. Add up the square footage of all walls to get the total square footage. Divide the total square footage by the square footage of a sheet of drywall to determine how many sheets you need.
Each sheet covers 48 square feet. Divide 1500 by 48 gives you 31.25 sheets of drywall.
Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.
You will need at least 14 sheets, depending on shape and height of wall.
To patch ceiling drywall effectively, start by cutting out the damaged area in a square or rectangular shape. Cut a new piece of drywall to fit the hole, secure it in place with screws, and then apply joint compound to smooth out the seams. Sand the area, apply primer and paint to match the rest of the ceiling.
I use about five pounds per 10 -12 sheets.
You need roughly 94 sheets, however, the shapes of walls and stairs will change that figure slightly.
