A square pyramid has a base area of 36ft2 the pyramids total surface area is 144ft2 what is the area of each triangular face?

So a square pyramid is like the pyramids in egypt so

surface area of pyhraid=base+4 triangles

surface area=144

baswe=36

subsitute

144=36+4 times triangles

subtract 36 from both sides

108=4 triggles

divide by 4

27=trignels

the area of 1 triangle is 27 ft^2
