Shemy placed three empty tanks side by side. The smallest tank has a crack at its side and the base area of each tank is 16 cm^{2}. After she turned on the tap for 64 minutes, the height of the water in the smallest tank became 6 cm although 0.5 mℓ of water is leaking out of the crack per minute. Find the rate of flow of water from the tap. Give the answer in mℓ/min.

A tank with a square base area of 121 cm^{2} is 60% filled with water. If 4 pails of water are poured into the tank, 756 cm^{3} of water would overflow. If 3 pails of water are poured into the tank, 128 cm^{3} of water would overflow. What is the height of the tank ? Give the answer to one decimal place.

The diagram shows 3 containers of different dimensions, each separated by a partition. Tank C, measuring 20 m by 15 m by 21 m, is filled with water to its brim. Tank B is an empty cuboidal container with a length of 10 m. Slider 1 is lifted to release ^{1}_{4} of the water from Tank C to Tank B, after which the partition is slid down to separate Tank C and Tank B. Next, Slider 2 is removed and some water from Tank B flows into Tank A such that the height of the water level of Tank B and Tank A is 7 m.

- What is the length of Tank A?
- How many m
^{3}of water are there in Tank B?

The figure is not drawn to scale. An empty Tank A measures 50 cm by 20 cm by 40.5 cm. Tank B with a base area of 1000 cm^{2}was completely filled with water. Ronald poured ^{1}_{2} of the water from Tank B into Tank A. The water filled 70% of Tank A. What was the height of Tank B? (Correct the answer to 2 decimal places.)

A rectangular tank measuring 35 cm by 26 cm by 12 cm is completely filled with oil. Oil from the tank is poured into an empty cubical container of edge 18 cm until the cubical container is half-filled. What is the height of the oil in the tank after some oil is poured out? Correct the answer to 1 decimal place.
