There are some formulas for pyramids for area and perimeter. There is also one if you have a 2D pyramid that has, lets say blocks for the base.

0

00

000

0000

Like that. There is a formula without the E, to find out how many 0's there are in the pyramid.

Total num.=((base num./2)+0.5)base num.

T=((n/2)+0.5)n

In this case the base num. is 4 because there are 4 0's on the bottom of the pyramid.

T=((4/2)+0.5)4

T=(2+0.5)4

T=(2.5)4

T=10

There are ten 0's in the above pyramid.

The area is base * height /2 a the perimeter is all the sides added together.
