: Water is flowing into a cuboidal reservoir at the rate of 70 l per minute. If the
reservoir is 126 m", find the number of hours it will take to fill the reservoir


​

Answer 1

Step-by-step explanation:

Given :

Rate of flowing of water into the reservoir is 70 litres per minute,

and volume of the reservoir is 126 m³.

\underline{Relationship }

1 m³ = 1 ml

1 litre = 1000 cm³

1 m³ = 1000000 cm³ = 1000 litres

If,

1 m³ = 1000 litres

so,

capacity of reservoir =126 × 1000 = 126000 litres

.

Water is being poured at rate of 70 litre per minute.

= (70 × 60) = 4200 litre per hour

Number of hours water will take to fill the reservoir

=

$\frac{126000}{4200}$

= 30 hours

Hence,

it will take 30 hours to fill the reservoir.
