The daily water demand of a three-storey flat is 1200 litres, 1050 litres and 950 litres respectively. Even after meeting this demand, a tank with the storage capacity of 25% of the demand for water is available only 2.5 metre long and 1.6 metre wide. How many metres deep should the tank be ?
Answers
Step-by-step explanation:
Given:-
The daily water demand of a three-storey flat is 1200 litres, 1050 litres and 950 litres respectively. Even after meeting this demand, a tank with the storage capacity of 25% of the demand for water is available only 2.5 metre long and 1.6 metre wide.
To find:-
How many metres deep should the tank be ?
Solution:-
The amount of water for daily need in three flats =1200 litres, 1050litres,950 litres
Total amount of water is required for three flats =1200+1050+950=3200 litres
The capacity of the tank for this demand=25% of the demand
=>25%of 3200 litres
=>(25/100)×3200
=>3200/4
=>800 litres
The capacity of the tank=800 litres
we know that 1000m³=1 litre
1 m³=0.001 litres
800 litres=800/1000 m³
=>0.8m³
The capacity of the tank=0.8m³
Length of the tank=2.5m
Breadth of the tank=1.6m
Depth of the tank =h m
Capacity of the tank=Volume of cuboid
=>lbh =0.8m³
=>2.5×1.6×h=0.8
=>h×4=0.8
=>h=0.8/4
=>h=0.2m
or h=0.2×100cm=20cm
Answer:-
Depth of the tank shoud be 0.2 m or 20cm
