The surface area of a sphere is given by

in our case r=10 units ( the radius). By substituting this value into the last formula, we have

which gives

On the other hand, the surface area of a cube is given by

where L is the length of one side, that is, L=10. Then, we have

By comparing both results, we can see that the surface area of our sphere is larger than the surface area of the given cube. So the answer is TRUE.
