no. it doesn't sound right. ok i changed the area formula to A(y)= (4/3)y now i think it's correct. thank you

if by L(x) you are talking about the area that needs to be integrated, then the area is (4/3)(3-y) since y is that unknown length above the dy section.

y= 0 starts at the very bottom of the triangle for this integral.

would this integral be correct? i can never understand the whole concept about which way y is
