The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.
So 6s^2 is the surface area. We can use this to find s.
6s^2 = 600
s^2 = 100
s = 10 cm
The answer would be $3472
To do this multiply 1 by 4, then 3 by 5. 4 over 15 is your answer.
33/20 as well as 1 and 13/20. First you look it up in the internet aka Google.
