Hi please help with an explanation as well, I’ll reward branliest!!!

Answer:
1. B = 6 m²
2. h = 2 m
3. V = 12 m³
Step-by-step explanation:
the base is a right triangle
Then
[tex]B=\frac{3\times 4}{2} =6\ m^{2}[/tex]
____________
The height of the prism is the length of the segment that join the base to its opposite face
Then
h = 2m (given)
___________
The volume of the prism :
[tex]V=B\times h=6\times 2=12 m^3[/tex]
