How many screws in a 4x8 sheet of drywall?
Oh, dude, you're really asking me how many screws are in a sheet of drywall? It's like asking how many sprinkles are on a donut. Anyway, typically you'd use about 32 screws in a standard 4x8 sheet of drywall, but who's counting, right?
How many 4 inch by 8 inch bricks are needed to build a walk 6 ft wide and 24 ft long?
Assuming you lay them all the same way.... 4x8 = 32, area of a brick. 6x24 = 144, area of the walkway. Now, the walkway is in square feet, so we need to multiply by 144 to change it to square inches. 144 x 144 = 20,736. Divide this by the area of the brick. 20,736 / 32 = 648 So you need 648 bricks to cover the entire walkway.
How many sheets of plywood to cover a 13by14ft floor?
Math problem or Real life would make a difference in the answer. In real life you have to "break the joints" on the floor joists, in a math problem, not so much. Plywood almost universally assumes 4'X8' sheets so 4X8=X sq/feet/per sheet Hint more than 30 sq feet less than 36 13' X 14'= Y sq/feet for the room hint more than 180, less than 186 so looks like the formula will be room size divided by sq feet per sheet Y/X= Answer more than 5 less that 8 sheets, if you are answering in whole sheets round up if not it does have a decimal.
