40, if it's exactly 5x8 and there's no cutting involved. So get at least 48.
2/5 - 3/8 = (2x8)/(5x8) - (5x3)/(5x8) = 16/40 - 15/40 = 1/40
Yes, you can use the facts about 5x4 and 1x4 to find 6x8. First, recognize that 6x8 can be broken down into (5+1)x8, which equals 5x8 + 1x8. Since 5x8 is the same as 5x(4+4), you can calculate that as 5x4 + 5x4, and then add 1x8 (which is 8). This way, you can use the known facts to help find the answer.
5 + 5 x 8 = 45
40 square feet
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22

5*8 = 40
The two products are 5x8 and that equals 40.
