Discuss the relationship between the surface area and volume of a solid when scaled.

• The surface area decreases while the volume increases when scaled

• The surface area increases while the volume decreases when scaled

• The surface area and volume have no relationship when scaled

• The relationship between the surface area and volume of a solid when scaled is that they are both scaled by the square of the scaling factor, maintaining a constant ratio.

Explain how scaling affects the ratio of surface area to volume in solids.

• Scaling increases the ratio of surface area to volume in solids

• Scaling has no effect on the ratio of surface area to volume in solids

• Scaling decreases the volume of solids without affecting the surface area

• Scaling affects the ratio of surface area to volume in solids by decreasing the ratio as the solid is scaled up.
