One square foot is 12in x 12in which means one square foot is equal to 144 square inches. 

If 8 pieces of glass = 144 square inches
then let's multiply both sides since 144 x 6 = 864

(8 pieces of glass) x 6 = (144 square inches) x 6
so 48 pieces of glass = 864 square inches

The answer is B 48 pieces

First, you get your inches to feet by dividing 864 by 12 twice which equals 6.  Because there are 8 pieces of glass per square foot, we multiply 6 by 8, which equals 48 :)  so, your answer is 48
