The surface area of a particular cube is 600 square inches. When the
edges of the cube are doubled in length, what is the volume of the
new cube, in cubic inches?

The volume of two cubes is proportional to the cube of their sides
since you increased the side by a factor of 2
the volume will increase by a factor of 2^3
Can you find the side of the original cube knowing its surface area is 600 ?

100 because when you multiply 6 by 100 you will get 600
