Question

Find the lateral area for the regular pyramid.

Answer 1

Lateral area = 1/2 * perimeter of base * slant height

1/2 * 36 * 10 = 180

Lateral area = 180 units squared

Answer 2

thank you! could you help me find the total area as well? @nick111987

Answer 3

You mean the surface area?

Answer 4

Surface area = Lateral area + the area of the base

So 180 + ( 1/2 * 12 * 12 )
180 + 72 = 252

Surface area = 252 units squared

Answer 5

im not sure if that's it, it says total surface area and its like this

Answer 6

@nick111987

Answer 7

Yeah, that would be correct then ;)

Answer 8

but since I need it to be in an equation form would it be 180+72=252 sq. root?

Answer 9

No square roots are used for regular pyramids.

Answer 10

but my answer has to be in that format its like _ _ + _ _ = __sq root

Answer 11

I don't know then, sorry. Square roots are used in cones, not pyramids, so I'm confused too

Answer 12

okay well thanks.

Answer 13

No problem. You might check other problems that you got right and then use that to infer what number to use for that format.

Answer 14

do you know how to find the total area of this one? @nick111687
