    The "base" of a prism is a two dimensional region. Did you mean that the base is 11 square cm?

    I think that the OP meant that the "base" of the triangle cross section is 11cm, the altitude/height of the triangle cross section is 10cm, and the depth/height of the prism is 15cm.

    Without a diagram it's a bit hard to decipher...

    volume=1/2*length*width*height =1/2*15*10*11cm^3= 825 cm^3
