Question

What is the volume of a triangular prism​

Answer 1

`\large\boxed{V=630\ mm^3}`

Explanation:

The formula of a volume of a prism:

`V=A_BH`

`A_B-area\ of\ a \ base\\H-height`

In the base we have the right triangle. Calculate the area:

`A_B=(1)/(2)bh`

`b-base\\h-height`

We have b = 15 mm and h = 12 mm. Substitute:

`A_B=(1)/(2)(15)(12)=(15)(6)=90\ mm^2`

Calculate the volume:

`A_B=90\ mm^2,\ H=7\ mm\\\\V=(90)(7)=630\ mm^3`
