Question

Please help me answer this question! :D It will be greatly appreciated.Question:Find the lateral surface area of the square pyramid.

Answer 1

we know that

The lateral surface area of a square pyramid is equal to the area of its four lateral triangular faces

so

`\begin{gathered} LA=4\cdot\mleft\lbrace(1)/(2)\cdot5\cdot8\mright\rbrace \\ LA=80in^2 \end{gathered}`

therefore

the lateral area is 80 square inches
