I don't think that you can. Integers are either positive or negative real numbers without decimals, so there isn't anything to simplify.
First solve for 16x20. 16*20= 320 inches. Now subtract the area that is removed, the 8x8 square. 8*8=64. 320-64=256. Our answer is 256in^2.
The answer would be -7/8. Hope this helps!
Consider the cup a cylinder. The formula for the volume of a cylinder is: V= PI x r^2 x h
Cup A: 3.14 x 7 x 1.5^2 = 49.46
This is large enough
Cup B: 3.14 x 5 x 1^2 = 15.7
This is too small
Cup C: 3.14 x 6 x 1.25^2 = 29.44
This is too small.
