Answer:
The height of the prism is 9yd.
Explanation:
The volume of the prism is
Vol
= BaseArea×height
The area of the base is the area of the triangle.
Area_triangle
= 1/2 b•h
= 1/2•8•7
= 28
28 is the BaseArea of the prism.
Again the volume of the prism is:
Vol = BaseArea•h
This h is the height of the prism. That is what we are looking for.
Fill in what we know or calculated already.
252 = 28•h
Divide by 28
9 = h
The height of the prism is 9yd.
