Can an expert me find the surface area of this pyramid

The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.

if the base is 12cm and the slant heights is 10cm then the total surface area is 168cm²

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
