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: A. 6.0cm
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
