Question

you have a graduated cylinder, which is filled with water up to 150 ml mark. you add a hunk of iron, and the water level rises to 425 ml. what is the volume of the piece of iron?
150
2160
275
425
7.87

Explanation:

Step1: Recall displacement method

The volume of the iron equals the increase in water volume.

Step2: Calculate volume change

Subtract initial volume from final volume: $425 - 150 = 275$ (mL). Since 1 mL = 1 cm³, the volume of iron is 275 cubic units.

Answer:

275
