A pyramid with a square base measures one yard on a side. The height of each triangular face is two yards. The surface area of the pyramid is Answer
square yards.

Answer 1

`SA=5\ yd^2`

Explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces

so

`SA=b^2+4[(1)/(2)(b)(h)]`

we have

`b=1\ yd\\h=2\ yd`

substitute

`SA=1^2+4[(1)/(2)(1)(2)]`

`SA=5\ yd^2`
