Question 42075: Question
An open water tank with length 20 cm and width 15 cm holds 4.8 litres of water. Calculate the height of the water level in the tank and the total surface area of the cuboid in contact with the water.
This is what I have done
4.8 litre = 4800 cm^3 (cm cube) since 1 litre = 100cm^3
Let the height of the water level = h
Volume
= Length x width x height = 4800
20 x 15 x h = 4800
300h = 4800
h = 4800/300
h=16
Total surface area of the cuboid
= 2 ((length x width) + (length x height) + (width x height))
= 2 ((20 x 15) + (20 x 16) + (15 x 16))
= 2 (300 + 320 + 240)
= 2 (1100)
= 2200
But my teacher said that the answer is 1420 (for the total surface area). Who is right in this case ?
Please help. Tahnk you very much.
