First find the area of the triangle shape:

Area of a triangle = 1/2 x base x height:

Area = 1/2 x 4 x 3 = 6 square cm.

For the volume multiply the area by the depth:

6 x 2 = 12 cubic cm

if we consider 1 same structure on above this so it's look like rectangular box
so,
volume of rectangular box = b×h×l
= 2×3×4
=24
now make half of this = 24/2=12cm^3
