An empty rectangular tank is 250cm long and 120cm wide. If 180 litres of water is poured into the tank. Calculate the height of the water
-
A.
6.0cm -
B.
5.5cm -
C.
5.0cm -
D.
4.5cm
Correct Answer: Option A
Explanation
Volume of water in tank = l x b x h = 180 litres
but 1 litre = 1000cm2
250 x 120 x hw = 180 x 1000
hw = (frac{180 times 1000}{250 times 120})
= 6cm
