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.
Volume = (Base x Height x Length) / 2

Volume = 216ft³
Rounding this to the nearest whole unit gives us the answer of 432ft³.
