Answer:
5190 g
Step-by-step explanation:
Calculate the volume:
28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³
Density is mass divided by volume:
D = M / V
Solving for mass:
M = D V
Substituting values:
M = (10.50 g/cm³) (493.92 cm³)
M = 5186.16 g
Rounding to three significant figures, the mass is 5190 g.

Answer:



And finally we can convert this into money like this:

So they spent every day approximately in total $ 4815291.6 dollars
Step-by-step explanation:
For this case we can convert the average power into Kw like this:

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

And now we know the total population so then the total consumption per day would be:

And finally we can convert this into money like this:

So they spent every day approximately in total $ 4815291.6 dollars
