Question

A square pyramid has sides of 8 m. Each face is an equilateral triangle.

What is the lateral area of the pyramid?

Answer 1

a) \[128\sqrt{3} m^2\]
b) \[128 m ^{2}\]
c)\[32 m ^{2}\]
d)\[64\sqrt{3}m ^{2}\]

Answer 2

do you know what's the Area of a Triangle?

Answer 3

if each triangular face is an EQUILATERAL triangle, then all sides must be "8"
so once you get the "altitude", use that to get the Area of each triangular face

SUM THEM UP, to get the Pyramid's LATERAL Area
