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
6.0cm
5.5cm
5.0cm
4.5cm
Correct answer is A
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
