Alfred used a bucket to fill an empty rectangular tank with water. He poured

4 buckets of water into the tank. The tank had a base measuring 80 cm by 30 cm.

He then decided to use a hose to fill the tank with more water until the water level

reached a height of 12 cm. Dennis came and took 2 buckets of water from the

tank. The water level fell by 1 1/2 cm.

(a)   What was the capacity of the bucket?

(b)   How much water in the tank was filled up using the hose?

HelloRobtlukas!

$$2V_{bucket}=8dm\cdot3dm\cdot0.15dm\cdot\frac{l}{dm^3}=3.6l$$

$$V_{bucket}=1.8l$$

(a) the capacity of the bucket was 1.8l.

$$4\cdot1.8l+x=(8\cdot 3\cdot1.2)l\\ x=21.6l$$

(b) 21.6l water in the tank was filled up using the hose.
