Ft. Then: Multiply the area of the house by the Price per Sq. Ft. So the cost of constrution on a house 40 by 30 ft long is \$64,800. For the question: how many 8 in square flagstones are needed for a patio 14ft long and 10ft wide? Yes you multiply 14 by 10: So the Patio is 140 Sq.Ft. wide. Now: Multiply 140 by 12 --so that the area will be in inches-- the patio equals 1,680 inches. NOW divide 1,680 by 8: (this is because you need to know how many 8-inch squares are in the 1,680 inch area) SO, There are 210 8-inch square Flagstones needed. Hope this is useful!
