**Problem Description:**

Find the volume of the given solid.

The solid is enclosed by the paraboloid \( z = x^2 + y^2 + 1 \) and the planes \( x = 0 \), \( y = 0 \), \( z = 0 \), and \( x + y = 4 \).

**Explanation:**

- **Paraboloid**: The equation \( z = x^2 + y^2 + 1 \) describes a paraboloid that opens upwards and is shifted 1 unit up along the z-axis.
- **Planes**:
  - \( x = 0 \): The yz-plane.
  - \( y = 0 \): The xz-plane.
  - \( z = 0 \): The xy-plane.
  - \( x + y = 4 \): A plane where any point \((x, y)\) satisfies the given equation, forming a line intersection in the xy-plane.

This setup involves calculating the volume of the region enclosed by the paraboloid and the given planes. The critical points of intersection will define the limits for the integral used to find the volume.
