Question

If a rock is submerged in water and the graduated cylinder read 100 mL, then a cylinder without the rock measures 75mL. What is the volume of the irregular shaped rock? Show your work and units.

Answer 1

25 mL

Explanation:

Archimedes's principle states that the volumen displaced of fluid by a body submerged in it equals to the volume of the body.

Therefore the change in volumen is:

`\DeltaV = 100-75 = 25` mL
