The answer is the first one. I am pretty sure.
Surface area is 34 units2 or sq.
the volume is 10 units3 or cubed.
volume is the amount of cubes on the inside, and the surface area is each surface added together
The <em><u>correct answer</u></em> is:
$54.75.
Explanation:
We only receive the discount if the majority of our usage occurs between 7 pm to 9 am. However, in the month of March we used 450 KWH between these hours and 465 KWH between 9 am to 7 pm; this means we lose our discount.
The rate per KWH is $0.05432; this means we pay
450(0.05432) = 24.444 for the hours of 7 pm to 9 am.
We also pay $0.05432/kwh for the hours of 9 am to 7 pm, but we have an additional 20% premium for the usage between these hours; this means we pay
465(0.05432)(1.2) = 30.31056, for a total of
24.444+30.31056 = 54.75456 ≈ 54.75
