Question

oma. The surface of this cube is cm2. Therefore, the surface-to-volume ratio is The volume of a cube with an edge length of 1 cm is ! The volumedf a cube with an edge kengh of 2cmis The volume of a cube with an edge length of 3 cmB Thus as the volume of an animal increases, its surface to volume ratio m. The surfece of this cube is cm3. The surfsce of this cube is cm2. Therefore, the surface-to volume ratio is Cm3. The surface of this cube is cm2. Therefore, the surface-to-volume ratio is As a consequence, relative to volume, a animal ill cool down faster

Explanation / Answer

1 . The volume with an edge length of 1 cm is 1 cm3. The surface of this cube is 6 cm2. Therefore the surface-to-volume ratio is 6.

2. The volume with an edge length of 2 cm is 8 cm3. The surface of this cube is 24 cm2. Therefore the surface-to-volume ratio is 3.

3. The volume with an edge length of 3 cm is 27 cm3. The surface of this cube is 54 cm2. Therefore the surface-to-volume ratio is 2.

4. Thus, as the volume of an animal increases, its surface-to-volume ratio decreases. As a consequence, relative to volume, a smaller animal will cool down faster.
