 221.4 m³  If you are just looking for the volume of the triangular prism.

Step-by-step explanation:  Volume of the prism is the Area of the base times the height.

The Area of the triangular base = width × height ÷ 2

Width = 12m   height =  4.1m = 49.2m Divided by 2 =

24.6m² is the Area of the base

The height of the base is 9m

24.6 × 9 = 221.4 cubic meters
