Given:
A figure of a triangular prism.
Height of triangular base =
yd
Base of triangular base = 4 yd
Height of prism = 4 yd.
To find:
The volume of the triangular prism.
Solution:
Volume of a triangular prism is:
...(i)
Where, B is the area of triangular base and h is the height of the prism.
Area of triangular base is:
![B=(1)/(2)* base* height](https://img.qammunity.org/2022/formulas/mathematics/high-school/rfr2bqm6fi0jz5nuka0babfw9pmz7vpbav.png)
![B=(1)/(2)* 4* 9(2)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/h59qwhcmucuzycqbs5j9deh28e62ylfz35.png)
![B=2* (29)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/cu0wec9kz8hre01bk7qcxayaw70la5mdo1.png)
![B=(58)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/v7zlh35j866zops3bd0obrdpzzi85nikkd.png)
Putting
and h=4 in (i), we get
![V=(58)/(3)* 4](https://img.qammunity.org/2022/formulas/mathematics/high-school/e8fh7jy73lspbfa5kntntyyqdn5hoe0v2d.png)
![V=(232)/(3)](https://img.qammunity.org/2022/formulas/mathematics/high-school/xq85raszovhre1c2g1cdzxj9t4ybd1gv9a.png)
![V=77.33...](https://img.qammunity.org/2022/formulas/mathematics/high-school/yw8i2a1r0v8ndy3m4sxjghri17chjdv10e.png)
![V\approx 77.3](https://img.qammunity.org/2022/formulas/mathematics/high-school/im2njuneho5be26d1cmgnnw2mnof0mxxbx.png)
The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.
