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:
![V_1=Length* Width * height](https://img.qammunity.org/2022/formulas/mathematics/high-school/ixdjtpm5ikao9unyjgig6sqomnlw8aou3z.png)
![V_1=16* 7 * 3](https://img.qammunity.org/2022/formulas/mathematics/high-school/iav7icrhlaywl4o9ysud9pyv5yif0kwl5i.png)
![V_1=336](https://img.qammunity.org/2022/formulas/mathematics/high-school/d4jhkuir52zvrdayyvrnv5jg5wxcncwaud.png)
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
![B=(1)/(2)* Base* Height](https://img.qammunity.org/2022/formulas/mathematics/high-school/4aqmtggi2tw6phwupjdtuwh9hojp325kyj.png)
![B=(1)/(2)* 3* 5](https://img.qammunity.org/2022/formulas/mathematics/high-school/z8ailpnuwpx5fdkejr3lw9gkd1aecwx20d.png)
![B=7.5](https://img.qammunity.org/2022/formulas/mathematics/high-school/lvy8gh344yn94aj84jfp3hiinb285mg0h6.png)
The volume of a prism is:
![V_2=Bh](https://img.qammunity.org/2022/formulas/mathematics/high-school/sprpb0qaxv8amptk2o0gxcry1yv4nfgu91.png)
Where, B is the base area and h is the height of the prism.
![V_2=(7.5)(6)](https://img.qammunity.org/2022/formulas/mathematics/high-school/m473yn2a4h4b50gbn15klsf0mcyt6774sm.png)
![V_2=45](https://img.qammunity.org/2022/formulas/mathematics/high-school/o87w192zecry0xk893njqy37jq43d3nvhb.png)
The volume of combined figure is:
![V=V_1+V_2](https://img.qammunity.org/2022/formulas/mathematics/high-school/f701nx1nhrvw3kynt7rc6ioypae8dxtv2s.png)
![V=336+45](https://img.qammunity.org/2022/formulas/mathematics/high-school/ilmffb1kktv9j3hymkx0qifbnwsch0wesm.png)
![V=381](https://img.qammunity.org/2022/formulas/mathematics/high-school/xndyyycegqsuiet9r05zohcng0vtawhcsq.png)
Therefore, the volume of the figure is 381 cubic in.
