By triangular prism , I understand it to be a triangular base.

You have given me only 2 sides of the base, unless the two sides are sides of a right-angled triangle, I cannot find the area of the base.

So I will assume it is right-angled.....

area of base = (1/2)(10)(15) = 75 cm^2

Then the volume = 75(10) or 750 cm^3
