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
The correct answer is: A
Explanation
Volume of water in tank = l x b x h = 180 litresbut 1 litre = 1000cm2
250 x 120 x hw = 180 x 1000
hw = \(\frac{180 \times 1000}{250 \times 120}\)
= 6cm
