Question

The square pyramid had a base edge of 1 meter. The height of each triangular face is 1 meter. What is the pyramid's surface area?

Answer 1

check the picture below.

so the pyramid looks more or less like so, notice, each triangular face has a base of 1, and a height of 1.

the total surface area of the pyramid is just, the area of all four triangular faces plus the area of its squarish base.


`\bf \stackrel{\textit{squarish base's area}}{(1\cdot 1)}~~~~+~~~~\stackrel{\textit{triangular faces' area}}{4\left[ (1)/(2)(1)(1) \right]}`
