Question

Amelia uses 6 pieces of fabric per square foot to make a blanket.

How many pieces of fabric will she need to make a blanket that is 720 square inches?

Answer 1

30 pieces of fabric are needed for 720 square inches blanket.

Step-by-step explanation:

Given,

Fabric used for 1 square foot = 6 pieces

1 foot = 12 inches

1 square foot = (12 inches )² = 144 square inches

Therefore;

144 square inches = 1 square foot

1 square inch = $\frac{1}{144}\ square\ foot$

720 square inches = $\frac{1}{144}*720 = 5\ square\ foot$

Pieces required for 5 square foot = 6*5 = 30 pieces

30 pieces of fabric are needed for 720 square inches blanket.
