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 = 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 = 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
