Answer:
B. -21a-15
Step-by-step Explanation:

Answer:
V = 540 inches ^3
Step-by-step explanation:
The area of the base is found be finding the other leg
a^2 +b^2 = c^2
12^2+b^2 = 15^2
144 +b^2 = 225
b^2 = 225-144
b^2=81
Take the square root of each side
b = 9
We can find the area of the triangle
B = 1/2 (9*12)
B =54
The Volume is given by
V = Bh
V = 54*10
V = 540 inches ^3
