Question

Please help! I really need it

Answer 1

To find the volume of a triangular prism:

⇒ necessary to know the formula

`Volume = (Area-of-Triangular- base)*(length)`

Let's first find the area of the triangular base:

⇒the formula for the finding the area of a triangle is ⇒
`(1)/(2)bh`

• b: length of base --> 3mm
• h: length of height: 6mm

Area of the triangle is
`(1)/(2)*3*6=3*3=9`

Since the area of the triangular base is 9 and the length is 5.22

⇒ the volume is:

`Volume = 9 * 5.22=46.98mm^3`

When the volume is rounded to the nearest tenth, the volume is 47.0
`mm^3`

Hope that helps!
