**Problem Statement:**

Find the volume of the solid under the surface \( z = 1 + x^2 y^2 \) above the region enclosed by \( y = x^2 \) and \( y = 1 \).

**Explanation for Educational Context:**

This problem involves calculating the volume of a solid bounded by a specific surface and a region in the xy-plane. The surface is described by the equation \( z = 1 + x^2 y^2 \), which is a three-dimensional shape.

**Region Description:**

1. **Boundary Curves:** 
   - The parabola \( y = x^2 \).
   - The horizontal line \( y = 1 \).

2. **Enclosed Region:**
   - The region of interest is where the graph of \( y = x^2 \) intersects and is beneath the line \( y = 1 \).
   - This creates a bounded area in the xy-plane which serves as the base above which the solid extends to the surface described by \( z \).

**Process for Finding Volume:**
- Set up the double integral with the region as the limits of integration.
- Integrate the given surface equation over this specified region to find the volume of the solid.

This exercise involves concepts from calculus, particularly integration and three-dimensional coordinate geometry.

Expert Solution
Step 1

Consider the given surface

z=1+x2 y2

Since,

y=1 and y=x2

Then,

x=±1

That is,

-1x1  and    x2y1
