Homework Help: math

Posted by Anonymous on Sunday, April 12, 2009 at 3:40am.

A school is soundproofing a band room with insulating tiles. The room is rectangular and is 30 feet long, 40 feet wide, and 12 feet high. All four walls, the floor and the ceiling will be covered, but a window that is 10 feet long by 4 feet high will not be covered. How many square feet of tiling is needed? If each tile is 8 inches by 8 inches, how many tiles should be ordered?

thanks =)
