**The Moscow Papyrus and the Volume of a Truncated Square Pyramid**

The Moscow Papyrus gives a formula for the volume of a truncated square pyramid as:

\[ V = \frac{h}{3} (a^2 + ab + b^2) \]

where \( h \) denotes the height of the truncated pyramid, \( a \) the length of the lower base, and \( b \) the length of the upper base, respectively. Assuming that the volume of a square pyramid is given by \( V = \frac{ha^2}{3} \), prove that the above formula is correct.
