To find the volume of the cylindrical container, we use the formula for the volume of a cylinder:

\[
V = \pi r^2 h
\]

Given:
- Diameter of the cylinder, \( d = 42 \, \text{cm} \)
- Height of the cylinder, \( h = 40 \, \text{cm} \)
- Use \(\pi = \frac{22}{7}\)

First, calculate the radius:

\[
r = \frac{d}{2} = \frac{42}{2} = 21 \, \text{cm}
\]

Now, substitute the values into the formula:

\[
V = \frac{22}{7} \times (21)^2 \times 40
\]

Calculating step-by-step:

1. Calculate \( 21^2 \):

   \[
   21^2 = 441
   \]

2. Multiply by 40:

   \[
   441 \times 40 = 17640
   \]

3. Multiply by \(\frac{22}{7}\):

   \[
   V = \frac{22}{7} \times 17640 = 55440 \, \text{cm}^3
   \]

So, the volume of the water container is:

\[
\boxed{55440 \, \text{cm}^3}
\]

Would you like more details or have any questions? Here are some related questions:

1. How would the volume change if the diameter were increased?
2. What would be the volume if the height was doubled?
3. How can you convert the volume from cubic centimeters to liters?
4. How does changing \(\pi\) to 3.14 affect the calculated volume?
5. Can you calculate the surface area of the cylinder with the same dimensions?

**Tip:** Always ensure you correctly substitute values into formulas to avoid calculation errors.
