First multiply the 5.38 and 4.2 together to get 22.596. We will deal with it in a bit. For the bases of 10, we will add the exponents giving us 10 to the 7th power. So this is what we have so far:

. But that decimal number has to be between 1 and 10 and it's too high so we have to move the decimal one more place to the left. When we do that, we are adding one more power to the 10. The final answer in scientific notation is

I hope this helps!
It's just saying that you need to find the volume and surface area and then write them in the designated area, which will be on the side or the bottom.

For example:
When you got 722, you can just find another square that might say 722 on square area or volume, then just put the numbers together on the same side.
I don't know if this helped but I hope it did!
