A rectangular tank is 40 cm long, 25 cm wide and 30 cm tall. Water fills the tank to a height of 12 cm. A metal block of volume 3 000 cm³ is then fully submerged in the tank without any water overflowing. By how many centimetres does the water level rise?

Worked Solution
Step 1: Find the base area of the rectangular tank.
40 × 25 = 1 000 cm²
Step 2: The volume of the submerged block equals the volume of water displaced.
Rise in water level = volume of block ÷ base area
= 3 000 ÷ 1 000
= 3 cm
The water level rises by 3 cm.
Correct answer: 3 cm
