How many 4′ * 8′ sheets of drywall do you need for the walls of a 12′ * 20′ room, 8 ft high?

Thursday, October 15th, 2009
I don’t know asked:


If ceramic tiles are 8 * 8, how many tiles would it take to cover an area 4′ * 6′?

If a customer buys 20 2 * 4’s 8ft long, at $4.75 each, how much would the 2 * 4’s cost?
