feet. How many quilt squares does he need?

Answer 1

We convert the dimensions of the wall hanging to inches, since that's the unit of measurement for the quilt squares:

1 yard = 36 inches
2 1/2 feet = 30 inches (since 1 foot = 12 inches)

So the dimensions of the wall hanging in inches are 36 x 30. To figure out how many quilt squares it will take to cover this area, we need to divide the area of the wall hanging by the area of each quilt square:

Area of wall hanging = 36 x 30 = 1080 square inches
Area of each quilt square = 3 x 3 = 9 square inches

Number of quilt squares needed = Area of wall hanging / Area of each quilt square
Number of quilt squares needed = 1080 / 9
Number of quilt squares needed = 120

Att will need 120 quilt squares to make the wall hanging.
