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
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
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
