Question

A rectangular water tank of dimension 4m x 3m x 1m is filled with water. Water from a tap flows into the tank at 1.5 litres a minute. How much water is in the tank after 60 minutes?
​

Answer 1

$x$Answer:

90 litres

Step-by-step explanation:

(1 $l$ =1000 $cm^{3}$)

1.5 litres = 1500 $cm^{3}$  

1 min --> 1500 cm^3

so 60 mins ---> $x$ $cm^{3}$

$x$ = 60 x 1500

$x$ = 90,000 $cm^{3}$   (1 $l$ =1000 $cm^{3}$)

$x$ = 90 litres
