Reed uses 8 pieces of glass per square foot to make a stained glass window. how many pieces of glass will he need to make a window that is 864 square inches? clear check 24 pieces 48 pieces 72 pieces 108 pieces

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
