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
Answer:
Y = 6 and x=6 are perpendicular because they both measure at a 90 degree angle
No beacuse 1/4 would be less that 1/2 it's common sense
