    1(a) The method to find volume is correct
    1(b) Why is the volume of pyramid is one third that of the cuboid?
    Do refer to the formula and see info is needed to find the volume of the pyramid.

    2. The approach to find the surface area is correct.
    The calculated value for total surface area is correct; however, the unit is incorrect.
