Answer: The volume of the pyramid is measured in cubic yards.
Step-by-step explanation: Given that the dimensions of a square pyramid are measured in yards.
We are to find the unit in which the volume of the pyramid is measured.
We know that
the volume of a square pyramid with length of base edge 'a' units and height 'h' units is given by

Here, length of base edge 'a' and the height 'h' of the given square pyramid is measured in yards.
Therefore, the volume of the pyramid will be measured in

Thus, the volume of the square pyramid is measured in cubic yards.
