If r, h is denoted radius, height pyramid then:

Volume of Pyramid

Volume is defined as the total space occupied by the three-dimensional shape or solid object. The volume is denoted as “V”. It is measured in terms of cubic units.

Volume = 1/ 3 × (Base Area) × height

Surface area of Pyramid

The surface area of a pyramid is the total area of all the surfaces, including the base area, perimeter and slant height, such as;

Surface Area = (base area) + (1/2) × (perimeter) × (slant height)
