Answer:
first choice
Step-by-step explanation:
The volume of a rectangular prism is L*H*B.
So the volume of the rectangular prism pictured here is 24*10*8
The volume of a triangle prism is 1/2 *H*L*B.
So the volume of the triangle prism pictured here is 1/2 *6*24*8
The volume of the whole figure is the sum of the volume of the rectangular prism and volume of the triangular prism which is in this case:
24*10*8 + 1/2 *6*24*8.
Answer is the first choice.
(It wouldn't be third because 10 has nothing to with the triangular prism part)
