I'm guessing these are two questions? Anyway, to find the volume of most prisms, you just do base area into height. Here,we have our work cut out for us since we already have base area.
For the one with the 9, 10 dimensions, the volume is (9x10) = 90cm^3
For the the one with the 14.5, 6 dimensions, the volume is (14.5x6) = 87cm^3
