What is Pyramid?
A pyramid is a three-dimensional object with flat faces. A pyramid's base is a polygon that is used to describe the pyramid (eg a square-based pyramid, triangle-based pyramid etc). It has triangular sides that connect at the top.
The volume of a pyramid is one-third of the product of its base and its height. Therefore, the volume of the pyramid with a base of 10×10 and a height of 81 units will be,
[tex]\rm \text{Volume of the Pyramid} = \dfrac{1}{3} \times (\text{Area of the base}) \times height[/tex]
[tex]\rm \text{Volume of the Pyramid} = \dfrac{1}{3} \times 10 \times 10 \times 81\\\\\rm \text{Volume of the Pyramid} = 2,700\ units^3[/tex]
Hence, the volume of the pyramid is 2,700 units³.
