we know ,

1 m³ = 1000 litres

so , volume of cuboid = 108 m³ = 108 × 1000 = 108000 litres

volume = 108000 litres

rate of flow of water in 1 minute= 60 litres

therefore , time it will take to fill whole reservoir = 108000/60 = 1800 minutes
since , 1 hr = 60 minutes

1 minute = 1/60 hours

=> 1800 minutes = 1800/60 = 30 hrs



volume = base area × height of cuboid

=> 108 m³ = 24 m² × height

=> 108 m³/ 24m² = height


=> 4.5 m = height of cuboid


hope this helps
