A manufacturer is developing cubic nanostructures for use in very small electronic components. The side length of nanostructure D is increased by a factor of 8 compared with nanostructure C.
What happens to the surface area to volume ratio of nanostructure D compared with nanostructure C, and which relationship explains the change?
It increases by a factor of 8 because a larger cube has a larger total surface area
It decreases by a factor of 8 because volume is directly proportional to side length
It stays the same because the surface area and volume both increase
It decreases by a factor of 8 because the surface area to volume ratio is inversely proportional to the cube's side length
