❗️❔❗️what is the volume of the prism below?

If we had two of these they'd fit together to form a nice 5 by 7 by 8 rectangular prism, just like the last one.

So our area is (5)(7)(8)/2 = 35(4) = 140

Choice B

B.

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 :-

, 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 :-
