Answer:
Volume= 360 feet³
Explanation:
We have two shapes, a triangular prism and a rectangular prism.
Rectangular Prism:

So, the volume is 6×2×8=96 feet³
Triangular Prism:

So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³
We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³
