Poll

Have you learned how to calculate volume of objects in maths?

Yes, definitely

Maybe, but I am not clear on it

No

If the cylinder started with 100mL in it, what is the volume of the rock?

Calculations

​Because water is handy....

1mL of water = 1 centimetre cubed.
1mL of water = 1 gram

So when we are looking at volume of irregular objects, 25mL = 25 cm3

Math Response

If I start with a measuring cylinder that has 57mL of water in it, and I add an object that moves the water to 79mL, what is the volume of that object?
