### Volume of a Solid with Square Cross-Sections

**Description:**

The base of a certain solid is the area bounded above by the graph of \( y = f(x) = 9 \) and below by the graph of \( y = g(x) = 4x^2 \). Cross-sections perpendicular to the \( x \)-axis are squares.

**Graph Explanation:**

- **Base View:** The graph shows two functions: 
  - \( y = 9 \) (horizontal line), indicating the constant upper boundary.
  - \( y = 4x^2 \) (parabola), representing the lower boundary.
- **Cross-Section:** A vertical line segment is shown perpendicular to the \( x \)-axis, demonstrating the square cross-section.

**Formula for the Volume:**

To find the volume of the solid, we use the formula:
\[
V = \int_a^b A(x) \, dx
\]

**Steps to Calculate the Volume:**

1. **Lower Limit of Integration** (\( a \)):  
   *Enter value here*

2. **Upper Limit of Integration** (\( b \)):  
   *Enter value here*

3. **Side of Square Cross-Section** (\( s \)):  
   The side \( s \) of the square cross-section is the following function of \( x \):  
   *Enter formula here*

4. **Area of Cross-Section** (\( A(x) \)):  
   \[
   A(x) = \text{{side}}^2 \quad \text{(since it's a square)}
   \]

5. **Volume of the Solid** (\( V \)):  
   \[
   V = \int_a^b A(x) \, dx
   \]
   *Enter calculated value here*

This setup allows you to understand the bounds and calculate the volume using integration with respect to \( x \).
