    height h = 9 m

    slant height s = 9.0553851381374 m

    side length a = 2 m

    lateral edge length e = 9.1104335791443 m

    1/2 side length r = 1 m

    volume V = 12 m3

    lateral surface area L = 36.22154055255 m2

    base surface area B = 4 m2

    total surface area A = 40.22154055255 m2
