Answer: B. [tex]140\text{ units}^3[/tex]
Step-by-step explanation:
From the given picture it can be seen that, the height of the right triangle h= 5 units
The base of the right triangle b= 7 units
The length of the base l= 8 units
We know that the volume of the right triangular prism is given by :-
[tex]\text{Volume}=\frac{1}{2}bhl[/tex], where b is the base and h is the height of right triangle and l is the length of the rectangular base of prism.
Now, the volume of the given right triangular prism is given by :-
[tex]\text{Volume}=\frac{1}{2}(7)(5)(8)\\\\\Rightarrow\text{Volume}=140\text{ units}^3[/tex]
