The prism shown is 35 .

work out h, the height of the triangular cross section.

i need with this

The height of the prism is h=2.5 cm.

Given information:

The volume of the prism is .

The base of the prism is a rectangle with sides 4 cm and 7 cm. 4 cm side is the base of the triangular face.

So, the volume of the prim can be written as,

The value of h can be calculated as,

Therefore, the height of the prism is h=2.5 cm.

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

where

B is the area of the triangular base

L is the length of the prism

we have

substitute

solve for B

Find the height of the triangle

The area of triangle is equal to
