Question

you have 120 pieces of fabric to make a blanket. Each piece of fabric is a square with a side length of 6 inches. You use as many pieces of fabric as possible to create a square blanket. How many pieces are left over .

Answer 1

The biggest square that can be done with 120 squares is a 10 by 10 square, because an 11 by 11 square would need 121 pieces.

So, the answer would be to use 100 pieces to make a 10 by 10 square blanquet and we will have a leftover of 20 pieces
