Evan is making a quilt out of squares of material with sides measuring 6 inches. How many squares will he need to make a quilt that is 6 feet long and 5 feet wide? Note: 1 foot = 12 inches.

Answer 1

squares 1/2 ft by 1/2 ft = (1/2)^2 = 1/4 ft^2

6x5 ft = 30 ft^2

30/1/4 = 30(4) = 120 squares needed

or work the problem in inches

6x5 ft = 6(12) by 5(12) = 72(60) = 4320 in^2

divide that by 6x6 = 36 in^2

4320/36 = 120 squares
