triangle height - 4ft
prism height-9.5ft

A.23ft
B. 86ft
C.171 ft
D.342 ft
Help

Answer 1

V= l x w x h V= 9 x 4 x 9.5 342 ft = Volume D. 342 ft Hope this helps I read the question iincorrectly sorrry

Answer 2

The volume of any prism is just the area of the base times the height of the prism.

The base of the prism is a triangle, and you should know how to find the area of a triangle already. The base is 9, the height is 4,
`\frac{bh}2=\frac{9*4}2=\frac{36}2=\boxed{18\ ft^2}`.

Multiply that by the height of 9.5 and we get
`18\ ft^2*9.5\ ft=\boxed{\boxed{171\ ft^3}}`
