Given:
A figure that contains a right triangular prism and cuboid.
To find:
The volume of the figure.
Solution:
The dimensions of cuboid are 16 in, 7 in and 3 in.
So, the volume of the cuboid is:



The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is



The volume of a prism is:

Where, B is the base area and h is the height of the prism.


The volume of combined figure is:



Therefore, the volume of the figure is 381 cubic in.
