I read an e-book about the classical mechanics and didn't know how to find the lower and upper limits for a volume integral.
Perhaps, it may be related to the use of similar triangle.
The Attempt at a Solution
I calculated the x value only (y is the same as x because of symmetry)
z/h = x/(a/2) = 2x/a
x = az/2h (distance)
Lower Limit = -az/2h
Upper Limit = az/2h
Can anyone tell me how to obtain the same values as the one given by the author?
Thank you very much!
