To find the volume of a triangular prism, we need to use the formula:

Volume = (Base x Height x Length) / 2

Here, the base of the triangular prism is a triangle with base 12ft and height 2ft. So, the area of the base is:

(1/2) x 12ft x 2ft = 12ft²

The length of the triangular prism is 18ft.

Therefore, the volume of the triangular prism is:

Volume = (12ft² x 18ft) / 2
Volume = 216ft³

Rounding this to the nearest whole unit gives us the answer of 432ft³.
