The volume of a prism is given by its base area multiplied by its height.
The bases are two right triangles. If we project everything on the xy plane, we can see that the vertices of the base triangle is

So, leg AB is 3 units long, and leg AC is 4 units long. This means that the area of the triangle is

The height of the prism connects, for example, points
and
, so it's 5 units long. So, the volume of the prism is

You would do 7/8 x 8/1 which is 56/8 which simplifys to 7 so your answer would be 7
Answer:
(x-1) (x+4)
Step-by-step explanation:
x^2 +3x-4
What 2 terms multiply to -4 and add to 3
-1*4 = -4
-1+4 = 3
(x-1) (x+4)
