Answer:
112 cm
Explanation:
First find the area of the triangle. Formula: 1/2bh
Base of 8 times height of 4 = 32. Then you divide 32 by 2(or multiple by 1/2, it's essentially the same) to get 16.
Now that you've found the area of the triangle, you multiply that by the length of the shape. (7cm)
16*7 = 112
So the volume of the shape = 112cm^3
