a student used cubes of potato to investigate the effect of surface area and volume on the
rate of osmosis. the diagram shows two of the cubes of potato the student used.
2 cm
1 cm
1 cm
2 cm
cube 1
cube 2
the surface area to volume ratio of cube 1 is 6: 1.
(a) calculate the total surface area of cube 2.
total surface area of cube 2 =
cm2
