Question

If 5g of grass is required to cover an area of 1m square, then what is the weight of grass in kg required to cover a foodball field of dimensions 120m ×90m

Answer 1

Area of the football ground=120m ×90m
=10800 square m
Grass required to cover 1 m sq. of ground=5g
So, Grass required to cover 10800 m sq.= 5×10800=54000g
As we know 1g= 1/1000 kg
So,54000g =54000/1000=54kg
Therefore, 54 kg of grass is required...
