Question

What's the volume of the figure​

Answer 1

Answer:

b

Step-by-step explanation:

The volume (V) of the triangular prism is

V = area of triangular end × length

area of triangle = $\frac{1}{2}$ × 3.4 × 2.5 = 4.25 in², hence

V = 4.25 × 4.8 = 20.4 in³ → b

Answer 2

Answer: B

Step-by-step explanation:

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

$V=\frac{1}{2} *l*w*h$

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

$a=\frac{1}{2} b*h$

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