- Surface area of the 4 mm cube: 96 mm²
- Volume of the 4 mm cube: 64 mm³
- Surface area to volume ratio for the 4 mm cube: 1.5:1
- As the cube size increases, the surface area to volume ratio decreases.
- This affects diffusion because a lower ratio means less surface area relative to volume, making it harder for substances to diffuse into or out of the cell efficiently.
- Cells are small to maintain a high surface area to volume ratio, which supports efficient diffusion and exchange of materials necessary for cellular functions.
Parent Tip: Review the logic above to help your child master the concept of surface area to volume ratio worksheet.
