The question is impossible to answer since. Since you can't answer that without knowing the volume of the bar to start with. The only given is the length, there should be other dimensions like the width and area of the cross-section, for instance.
Volume = Width x Depth x Height in all cases, so when you know the volume. But to solve for the height of the cuboid, the equation is V/100 (because the base of the cuboid is 100 cm^2)
Surface area of a sphere is 4 times pi timers radius^2
aprox pi=3.14
so surface area=145,000,000
145,000,000=4 times 3.14 times rdaius^2
145,000,000=12.56 times radius^2
divide both sdies by 12.56
11544585.987=r^2
square root both sides
3397.73=radius
round to the hundreds
3397 rounded to the hundreds
3400
the answer is D 3,4000 km
