the problem:

Consider the region bounded by the planez=xand the surfacez=x2, and the planesy= 0 andy= 3.

Write an integral to find the volume of the region in the form .

I figured out A=0 B=1 C=0 and D=3 but im not sure how to get E and F

Can someone please explaing to he how i would get them and how to get f(x,y,z)

Thank you!
