The problem is giving a triangle, whose side are y from 0 to 2 and x from 0 to 4.

It wants me to integrate the function f(x,y) = x^2y within this boundary

So I chose for my constant of this function to be y is less than or equal to 2x and greater than or equal to 0. This is confirmed by an example in the book using an identical triangle

So i integrated the function with respect to x using these limit and go 8x^4/3

I then integrated between 0 and 2 with respect to y and go 256/15

this isnt right, and I cant seem to get a different answer than this

any help?
