Answer:
![\large\boxed{V=2520\ cm^3]()
Explanation:
The formula of a volume of a prism:

B - base area
H - height
In the base we have the right triangle.
The formula of an area of a right triangle:

a, b - legs
We have a = 7cm, b = 24cm.
Substitute:

Put the values of B = 84cm² and H = 30cm to the formula of a volume of a prism:
