Question

Determine the initial volume of water in the graduated cylinder. If you added the black marble to the graduated cylinder and it sinks what final volume should the water level indicate?

Marble is 14 cm cubed & cylinder initial volume is 105 mL. Please show the formula on how to arrive at the answer of 124 mL for the final volume so I can understand how to solve these types of problems going forward.

Thank you

Answer 1

1st: 14cm^3

2nd: 124 mL

Step-by-step explanation:

I got it wrong :/ that's the only explanation you need.

Answer 2

Initial volume mentioned = 105mL

Marble volume should be 19mL or
`19cm^3` instead of
`14cm^3`

That is,

Volume of the object (Marble) = Volume of water displaced

= 124 mL - 105 ml = 19 mL

The formula is

Volume of the object (Marble)

= final volume of water – Initial volume of water

So,

Final volume = Volume marble + Initial volume

= 19 mL + 105 mL = 124 mL

Please Note: 1mL=
`1cm^3`
