... 88 + 88 + 88 + 88 = 4×88 = 352
352 passengers are carried <em>to</em> the island each day.
_____
Some questions must be answered before we can give a definite answer.
1. If the same person rides twice, are they counted twice?
2. Are passengers on the return trips (<em>from</em> the island) counted?
3. If return trip passengers are counted, is the ferry full on those trips?
4. Does every passenger to the island return the same day?
5. Does any passenger go to the island more than once per day?
40/5 because to find the answer you would divided them
Surface area of a cube = 6l²
Now given length = l = 8 mm
= 6*8² = 6*64 = 384 mm².
Thank you !!
I'm pretty sure 10/63 is simplified.
