Answer:
5 hours
Step-by-step explanation:



But assuming integer hours only, round down to 5h. The cost will be $600.
So, let's take a look! When doing volume, we always do (addition) and nothing else. The only time that we would have to multiply is if we would have to find the area, but in this case, we are (going to figure) out what would be the volume.
We would sum up the following:

.
I believe that we would multiply this by (2) because we would have to find the other side as well.
And this would give us . . . 64 as it's volume.
V= (64)
The answer is 90
because increased means times so 30 + 30 = 60 + 30 = 90
