Question

a storage tank at a petrol station is a cuboid 4 m long, 3 m wide and 2 m deep. In one day if
alla 7200 litres of petrol from the tank, what is the fall in the level of the petrol in the tank?​

Answer 1

Answer:

0.0033

Total size of tank=4*3*2= 24

in 1 day if alla 7200 liters from tank

so the fall level of the tank is

=24/7200=0.0033

Answer 2

The fall in the level of the petrol in the tank is 0.6 m

Step-by-step explanation:

Length of tank = 4 m

Breadth of tank = 3 m

Height of tank = 2 m

Volume of tank = $Length \times Breadth \times height = 4 \times 3 \times 2 = 24 m^3$

Petrol used =  7200 liters

1 liter = 0.001 cubic m

7200 liters = $7200 \times 0.001 = 7.2m^3$

Amount of petrol left = 24 - 7.2 = 16.8 cubic m

Let the present level of petrol be h

So, $16.8 = 4 \times 3 \times h$

$\frac{16.8}{4 \times 3} = h$

1.4 = h

Change in height = 2 -1.4 = 0.6 m

Hence the fall in the level of the petrol in the tank is 0.6 m
