Aroof is shaped like a square pyramid. the base length is 10 meters and the slant height is 12 meters. what is the surface area?

Surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters

Solution:

Given that  

Shape of the roof is square pyramid.

Base length of square pyramid roof = 10 meters

Slant height of square pyramid roof = 12 meters

Need to calculate the surface area of the roof

Where s is side of square base and l is slant height.

In our case s = 10 meters and l = 12 meters

On substituting the given values in formula we get  

Surface area of square pyramid

Hence surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters.
