Question 1111455: A rectangular glass tank with a length of 20cm, height of 30cm, width of 25cm is half filled with water. By how much, in terms of centimetres, will the water level rise if a solid cylindrical piece of iron,
with a diameter of 6 cm and a length of 10 cm, is dropped into the water? The answer, rounded to two
decimal digits, is ...
[1] 0,57 cm
[2] 0,28 cm
[3] 2,26 cm
[4] 0,38 cm
l got 0.38
The water level rise is the volume of the cylinder divided by the area of the floor of the tank.
= = = 282.6 cm^3.
= 20*25 = 500 cm^2.
The water level rise = = = 0.57 cm (rounded to two decimals).
Answer. 0.57 cm. Option [1].
