Given:
Cost of the cloth=₹10/m2
Base edge of square pyramid = 10 m
Slant height of square pyramid = 10 m
The amount of cloth required to build the pyramid will be the lateral surface area of the pyramid.
Lateral surface area of the square pyramid
=4×(12×base edge×slant height)
=4×12×10×10
=200 m2
Hence, the total amount of money required
=10×200=₹ 2000
