Question

The base of a triangular prism (read: triangular prism!) has a base of 5 cm and a height of 8 cm. The prism itself has a height of 7 cm. What is its volume?

Answer 1

its 140.4ft ^3

Explanation:

Answer 2

The volume of any right prisim is given by
`V = A_b * h` where
`A_b` is the area of the base and
`h` is the height.

In this case, the base is a triangle and so its area can be found thus:

`A = (1)/(2) b * h`

So:

`V= A_b * h_p`

`V=((1)/(2) * {b} * h_b) * h_p`

`V=((1)/(2) * {5cm} * 8cm) * 7cm`

`V=20cm^(2) * 7cm`

`V=140cm^(3)`
