Final answer:
The surface area to volume ratio of a cube-shaped human cell with dimensions of 100μm x 100μm x 100μm is 6:1.
Step-by-step explanation:
The surface area to volume ratio of a cell can be determined by dividing the cell's surface area by its volume. In the case of a cube-shaped human cell with dimensions of 100μm x 100μm x 100μm, the surface area would be 6 sides of 100μm x 100μm each, resulting in a total surface area of 60000μm². The volume would be 100μm x 100μm x 100μm, which equals 1000000μm³. Therefore, the surface area to volume ratio is 60000μm²/1000000μm³, which simplifies to 6:1.
