johnnewman · Answer

you need to find X

anonymous · Answer

What is the formula for the second figure?

ask_if_im_a_ghost · Answer

The Area of any prism is the area of its base times its height (or length).
So the volume of the triangular prism is $$\frac{ 1 }{ 2 }\times x \times 4\times7$$

anonymous · Answer

Okay, I got 4.5=x

ask_if_im_a_ghost · Answer

That is correct, now just plug in x to find the volume of each figure.

anonymous · Answer

I got 81 for figure 1, and 63 for figure 2

anonymous · Answer

81-63=18, so I think it's correct

ask_if_im_a_ghost · Answer

Yes, that is correct.
