I will give Brainliest if you can prove whether the story of Archimedes and his method to find the density of the gold crown if true. Mass of crown = 2 kg
( the whole is covered in gold and it has 8 diamonds of 1 kg. ) Find its volume and use the density of each substance.
Disclaimer : The examples are not specified. Just find out the volume. Also wrong answer will be reported as well as be given 1 star and no thanks.

kg

Explanation:

kg you just move up and down the stairs

This is easy.

To find, let me provide first the densities of the materials given below :

Gold = 19,300 in kg and 13.9 in g

Diamond = 3520 in kg and 3.51 in g

Mass of whole crown = 2 kg.

Explanation:

Here we have to use the formula Density = Mass / Volume

So,

                                                          D = M / V

                                                          17.41 = 2 / V

                                                           V = 34.82 g

I gave answer in grams

So, still some work is left, lets do it.

Volume is given in grams, so I have to convert it to kilograms since you provided to answer it in Kilograms.

1 kg = 1000 g

2 kg = 2000 g

34.82 g = 34.82/1000

             =0.03482 in kg

Whole volume is 0.03482 cm^3.

the answer is kevlar

connect the batteries in series and hope
