The figure below shows two rectangular tanks, X and Y. $540\text{ cm}^3$ of water was poured into X and Y until the heights of the water levels were the same. What was the height of the water level in each tank? Ans: ___ cm

1. Calculate the base area of Tank X

$\text{Base area of X} = 6 \times 5 = 30\text{ cm}^2$

2. Calculate the base area of Tank Y

$\text{Base area of Y} = 15 \times 4 = 60\text{ cm}^2$

3. Calculate the total base area of both tanks

$\text{Total base area} = 30 + 60 = 90\text{ cm}^2$

4. Calculate the common height of the water level

$\text{Height} = \frac{\text{Total Volume}}{\text{Total Base Area}} = \frac{540}{90} = 6\text{ cm}$
