A graduated cylinder has a mass of 50 g when empty. when 30 mL of water is added, the graduated cylinder has a mass of 120 g. if a rock is added to the grand cylinder, the water level rises to 75 mL and the total mass is now 250 g. what is the density of the rock?

The answer to your question is:

a) The gold cube is larger.

b) lenght = 1.67 cm

Explanation:

Data

Platinum    density  21.45 g/cm3          100 gram cube

Gold           density  19.3 g/cm3            100 gram cube

Formula

           density = mass / volume

a) Calculate volume

           volume = mass / density

Platinum    volume = 100 / 21.45 = 4.66 cm3

Gold           volume = 100 / 19.3 = 5.18 cm3

b)  Volume = lenght³

   4.66 cm³ = lenght³

   lenght = ∛4.66

   lenght = 1.67 cm

1 - since it's a library, i'd like putting a sculpture from ancient greece, probably from the hellenistic epoch.

2 - i'd also like the statue to be from a famous person from that time, a philosopher of possible.

3 - i'd want the statue to be of a man sitting down on a tree stump with a book on his hands (either writing or reading), to demonstrate the love for reading.

4 - i'd also like to have the statue with a darkish colour and high contrast, as well as a statue that resembles balance and a little movement on his head if he is reading or on his hand if he's writing.

hope it ,
