Can someone please help me with this I need to show how I got my answer aswell (will give out brainliest)

12 in³

Step-by-step explanation:

From the diagram,

Volume of the prism = Area of the triangular base×height.

V = (ac/2)h Equation 1

Where V = volume of the prism, a = base of the triangle, c = height of the triangle, h = height of the prism

Given: a = 4 in, c = 3 in, h = 2 in

Substitute these values into equation 1

V = (4×3/2)×2

V = 6×2

V = 12 in³

Hence the right option is 12 in³ as shown in the question below
