The complete question is as follows:
1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?
2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?
Answer:
1 . Surface area to volume ratio = Â 3 : 1
surface area=  3 cm³ or (l = 1 cm) (1 cm x 1 cm x  3) (W = 3)
volume=  1 cm³  (1cm x 1cm x 1cm)
2. Surface area to volume ratio = Â 6 : 1
surface area=  6 cm³  or (1 cm x 1 cm x 6 )  (w= 6)
volume=  1 cm³
Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
