Question

Find the surface area of a square pyramid with a slant height of 23 and a base side measure of 10.

Answer 1

Help please? My semester ends tomorrow!

Answer 2

I believe the fomula is S=B1/2Pl

Answer 3

Where B is the area of the base
P is the perimeter of the base
and l is the slant height

Answer 4

is pretty much what you have

take a look at one face, the bottom/base is 10, going upwards, is really just a triangle

Answer 5

get the area of THAT triangle, now you have 4 sides, thus 4 triangles, add all those up

then add the bottom/base, which is just a 10x10 rectangle
