The volume of a prism which has an altitude of 10 units and has a right triangle base with a hypotenuse of 13 units and a leg of 12 units is:
A) 780 units cubed.
B) 600 units cubed.
C) 325 units cubed.
D) 300 units cubed.
The other leg = 5
And the area of the base is (1/2) (5) (12) = (1/2) * 60 = 30 units^2
And the volume of the prism is
Base area * Height = 30 * 10 = 300 units cubed
