Final answer:
The volume of the square pyramid is 196 m³.
Step-by-step explanation:
To find the volume of a square pyramid, you can use the formula V = (1/3) × base area × height. In this case, the base of the pyramid is a square with side lengths of 7 meters, so the base area is 7^2 = 49 square meters. The height of the pyramid is 12 meters. Plugging these values into the formula, we get V = (1/3) × 49 × 12 = 196 cubic meters. Therefore, the volume of the pyramid is 196 m³.
