Surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters
<u>Solution:</u>
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.
