To calculate the volume of the pond, which has a trapezoidal shape (since the bottom and top areas are different), you can use the formula for the volume of a frustum of a pyramid:

$V = \frac{h}{3} \times \left( A_1 + A_2 + \sqrt{A_1 \times A_2} \right)$

where:

• $V$ is the volume,
• $h$ is the height (depth) of the pond,
• $A_1$ is the area of the bottom,
• $A_2$ is the area of the top.

First, let's calculate the areas of the bottom ($A_1$) and top ($A_2$) of the pond:

$A_1 = 103 \, \text{ft} \times 164 \, \text{ft} = 16,892 \, \text{sq ft}$

$A_2 = 159 \, \text{ft} \times 200 \, \text{ft} = 31,800 \, \text{sq ft}$

Next, we calculate the volume:

$V = \frac{13 \, \text{ft}}{3} \times \left( 16,892 \, \text{sq ft} + 31,800 \, \text{sq ft} + \sqrt{16,892 \, \text{sq ft} \times 31,800 \, \text{sq ft}} \right)$

Let's calculate this step by step.The total volume of the pond is approximately 311,431.61 cubic feet.
