    If a pyramid has a base of B square units, and a height of h units, then the a Pyramid volume V is 1/3 B x h cubic units, or V = 1/3 Bh ... the Base has to be AREA so with a square base you would need to square the side length to be in squared form for this it needs to be V=1/3(8)^2 X (10) = 1/3(64)(10) ............ = 21.12 x 10 = ..........211cm^3

    v=a^2*h/3 so v=8^2*10/3
