A water tank is in the shape of a triangular prism with a base that has a height of 12 meters and a base width of 8 meters. The length of the prism is 10 meters.

To calculate the volume of the tank, first find the area of the triangular base using the formula:

$$ A = \frac{1}{2} \times \text{base} \times \text{height} $$

Then, multiply the area of the base by the length to find the volume using the formula:

$$ V = A \times \text{length} $$
