The formula for determining the volume of a square based pyramid is expressed as
Volume = 1/3 × base area × height
Since the base is a square, all sides would be equal. The formula for finding the area of a square would be applied. From the information given, length of each side of the square is 12 cm. Therefore,
Base area = 12² = 144 cm²
Height = 10 cm
Therefore,
Volume = 1/3 × 144 × 10 = 480 cm³
