1. The problem statement, all variables and given/known data

Computer the volume of the solid bounded by the xz plane, the yz plane, the xy plane, the planes x = 1 and y = 1, and the surface z = x2 + y2

2. Relevant equations

None.

3. The attempt at a solution

Since the solid is bounded by the xz plane, the yz plane, the xy plane, it is assumed that the values of x, y, and z all equal 0. And since x = 1 and y = 1, the limits of integration is:

0 $$\leq$$ x $$\leq$$ 1

0 $$\leq$$ y $$\leq$$ 1

Thus, the double integral is:

$$\int$$ $$\int$$ x2 + y4 dA

and the limits of integration is 0 $$\leq$$ x $$\leq$$ 1, 0 $$\leq$$ y $$\leq$$ 1.

After calculating the integral, I got the answer $$\frac{8}{15}$$. Can anyone verify my work?

That's what I get, too.

For future reference, here is the integral I evaluated, using LaTeX.
$$\int_{x = 0}^1 \int_{y = 0}^1 x^2 + y^4~dy~dx$$
