1 cubic meter = 100 cm * 100 cm * 100 cm = 1 x 10^6 cc
1 kilogram = 1,000 grams
13.6 g / cc
If we had a cubic meter of mercury, its mass would be (or it would "weigh") 13.6 * 1,000,000 = 13,600,000 grams or 13,600 kilograms.
And so its density would be 13,600 kg / cubic meter.
Imma need more information on this?
Answer:

Step-by-step explanation:
Solve for the value of
:

-Multiply both sides by 


So, therefore, value of
is
.
The answer is 17. 30-13=17.
