The required volume of the pyramid is 42 m³.
Given that,
The volume of the pyramid is to be determined, the length of the side of the square base is 4 m and the height of the pyramid is 9 m.
What is volume?
Volume is defined as the ratio of the mass of an object to its density.
The volume of the figure is also given by the product of the height and cross-sectional area of the profile of the figure.
Area of the base = 4 × 4 = 16 m 2.
the volume of the pyramid,
= B * h/3
= 16 * 9/3
= 16 * 3
= 48 m³
Thus, the required volume of the pyramid is 42 m³.
