Level 3 PSLE
A and B are two rectangular tanks. The base area of A is 80 cm
2 while that of B is 50 cm
2 . At first, A contained water to a height of 40 cm and B was empty, as shown.
- What was the volume of the water in A at first?
- Rashid then poured some water from A to B. After that, the height of the water level in A was twice that in B. What was the new height of the water level in A? Round off the answer to 1 decimal place.

The figure is not drawn to scale. A and B are two rectangular tanks. The base area of A is 50 cm2 while the base area of B is 40 cm2. Tank A and B contained some water and the height of the water level in Tank A was 43 cm as shown. Dan then poured some water from Tank A into Tank B. After that, the height of the water level in both tanks became 30 cm. What was the height of the water level in Tank B at first?
