Question

a vessel inthe shape of a cuboid is 30 cm long & 25 cm wide.how high must it be,to hold 4.5 litres of water

Answer 1

1 metre cube = 1000 litres

so , 1 cm cube = 10 ^ -3 litres

so , 1 litre = 1000 cm cube
volume of a cuboid = 30 * 25 * h

30 * 25 * h cm cube = 4.5 * 1000 cm cube
h = (4500)/(750)
   = 6 cms.

Answer 2

Answer:

Answer is 6 cm

Step-by-step explanation:

1 litre= 1000 cubic cm

4.5 l = 4.5 × 1000= 4500 cubic cm

volume of cuboid vessel = length× breadth× height

4500= 30×25×h

h = 4500/30×25

h = 6 cm
