Hi so the easiest way you can do it is
Step 1:Multiply normally, ignoring the decimal points put the decimal point in the answer.
Step 2: then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined. Hope that help!
The side of a cube when the diagonal is known is found using the formula:
Side = √3 * diagonal/3
Replace diagonal with 20:
Side = √3 * 20/3
Side = √3 * 6 2/3
Side = 11.547 cm (Round the answer as needed).

Plug in jahiems age (14) for j and solve for c
assuming the last guest left at 6:32pm thus that'll be the duration of the party.
from 4:30 to 5pm is only 30 mins, from 5 to 6:32 is 1hr and 32 mins, now let's add the 30 mins from before, 1hr + 32 + 30, that's 1hr and 62 minutes, or namely 2hrs and 2 minutes.
