Question

What's the volume of the figure​

Answer 1

Answer: B

Explanation:

The volume of a triangular prism can be achieved by the equation:

`V=(1)/(2) *l*w*h`

similar to finding the volume of a regular right triangle, where you have:

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

Here all you are adding is the dimension of depth by multiplying that depth (l) by the equation for the area.

Answer 2

b

Explanation:

The volume (V) of the triangular prism is

V = area of triangular end × length

area of triangle =
`(1)/(2)` × 3.4 × 2.5 = 4.25 in², hence

V = 4.25 × 4.8 = 20.4 in³ → b
