When we calculate the surface area of the pyramid below we take the sum of the areas of the 4 triangles area and the base square the height of a triangle within a pyramid is called the slant height the volume of a pyramid is one third of the volume of a prism vfrac13cdot bcdot h the base of a cone is a circle and that is easy to see the lateral surface of a cone is a parallelogram with a base that is half the circumference of the cone and with the slant height as the height . When we calculate the surface area of the pyramid below we take the sum of the areas of the 4 triangles area and the base square the height of a triangle within a pyramid is called the slant height the volume of a pyramid is one third of the volume of a prism vfrac13cdot bcdot h the base of a cone is a circle and that is easy to see the lateral surface of a cone is a parallelogram with a base that is half the circumference of the cone and with the slant height as the height . The height of the prism is 8 inches we can use our formula to find the volume of the prism now consider a pyramid with a square base that has an area of 16 square inches and height of 8 inches.
