Question

A square pyramid with equilateral triangle.how find total surface area of the pyramid

Answer 1

Since it is square all sides, faces & area must be equal. Now since its pyramid having a top with an equilateral triangle therefore it's top face shall not be counted. If there are 6 faces in a cube and we remove a face we are left with only 5 faces. Now if it is an equilateral triangle therefore it must be having all sides, faces & area equal and 1 face covered out of 4. Thus we are only left with 3. Now calculate the surface area of a single square and multiply it by 5 then calculate the surface area of the triangle and multiply it by 3. Add the result of both you will get the total surface area. Simple! Logical & Brainly question.
