Question

Study Surface Area and Volume of Pyramid and Cone1. How to find lateral area and total surface area of pyramid?

Answer 1

Step-by-step explanation:

Lateral area of pyramid

Lateral area of squared pyramid is the sum of areas of its side faces.

`\begin{gathered} L=2al \\ \text{a is base length} \\ l\text{ is slant height and it is given as,} \\ l=\sqrt[]{(a^2)/(4)+h^2} \\ \text{Here, h is height of pyramid.} \end{gathered}`

Total surface area of pyramid

It is sum of the areas of its lateral faces and its base.

`\begin{gathered} \text{Total surface area=}(1)/(2)pl+B \\ p\text{ is perimeter of base} \\ l\text{ is slant height} \\ B\text{ is base area} \end{gathered}`
