Answer:
9 yd
Step-by-step explanation:
A cube consists of 6 square faces.
Divide the surface area by 6 for the area of one face
486 ÷ 6 = 81 yd²
The area of a square is
A = s² ( s is the side length )
Here A = 81, then
s² = 81 ( take the square root of both sides )
s = 
= 9
Thus side length is 9 yd

Answer:
You will need 50.54 liters of gas.
Step-by-step explanation:
This question is solved by proportions.
495km trip:
The gas efficiency is given in miles per gallon, so we need to find the number of miles traveled.
Each km has 0.6214 mi, so 495 km will be 495*0.6214 = 307.593mi.
Number of gallons:
23.0 mi/gal.
So for 307.593mi, the number of gallons is 307.593/23 = 13.37 gallons.
How many liters?
Each gallon has 3.78 liters.
So 13.37 gallons will have 13.37*3.78 = 50.54 liters.
