A block has dimensions 1.0 dm, 4.2 cm, and 25 mm, with a mass of 5.326 kg. Calculate the density of this block in g/cm 3 .

1 dm equals about 10 cm

25 mm equals 2.5 cm

and then we have 4.2 cm, including a mass of 5.326 kg

How do we find the density of the block?

First, lets rewrite our formula.

d = mass divided by volume.

lets multiply 10 cm x 2.5 cm x 4.2 cm

this equals 105.

Now, lets turn 5.326 kg into what we need to divide.

1000 cm x 5.326 kg is 5326 cm

now lets do 5326 into 105

thats 50.  

Explanation:

50 is the answer.

the answer is 303.15 or 303

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
