Find the area ratio of a cube with volume 125 m to a cube with volume 64 m.

So to find the ratio of the *Surface areas you need to find the Area of the sides/faces of the cubes.

*Keep in mind that the faces of a cube are squares.

Surface Area of a cube = Area of a side * 6
Area = length * width
Area of a square = length * length 

We don't know the length/width of the cube, so we need to solve for it using the values for the volumes of the two cubes.



Now find the area of the sides:



Now find the ratio between the Surface areas:


Thus the answer is 25/16 = 1.5625
