Answer:
95 seconds
Step-by-step explanation:
At 5 seconds per box, pulling 3 boxes takes 3×5 = 15 seconds.
At 1 second per envelope, pulling 10+10+60 = 80 envelopes takes 1×80 = 80 seconds.
The total time required to provide the required envelopes is 15 +80 = 95 seconds.
If the number is n then
square of 2 times a number
square of 2n
(2n)²
that was your mistake, because (2n)²=4n², not 2n²
the result is 81
(2n)²=81
square root both sides
remember positive and negative roots
2n=+/-9
divide by 2
n=+/-4.5
n=4.5 or -4.5
This is a 3-D container and the dimensional factor is F=3. The volume increases by a factor of 33 = 27.
The answer is 4608 x 27 / 123 = 72
