Dimensions of Cell Surface Area Volume Surface Area to Volume Ratio
5 mm x 5 mm x 5 mm 150 125 150:125 (150/125=6/5)
2 mm x 3 mm x 4 mm 36 24 36:24 (36/24=3/2)

above is what I think are the answers based on the table, I know that I got the surface area wrong, I'm not really sure how to find the surface area and volume of a cell... if anyone could help me with this it would be extremely helpful!

5 x 5 x 5 is a cube. A cube has all square faces. Each face's area is 5 x 5 = 25. A cube has 6 faces, so 6 x 25 = 150 mm². The volume is 5 x 5 x 5 = 125 mm³.

See attached diagram for next cell.

There are 6 faces to the 3d shape. Their areas are: (2 x 3) + (2 x 4) + (3 x 2) + (3 x 4) + (4 x 2) + (4 x 3) = 6 + 8 + 6 + 12 + 8 + 12 = 42 mm².

The volume is 2 x 3 x 4 = 24 mm².

for the second volume wouldnt it be 52?? because 6 + 8 + 6 + 12 + 8 + 12 = 52 not 42?

Sorry, my mistake!

its all good , thank you so much ! I was having so much trouble trying to figure out how to calculate the surface area and volume of a cell!! Thanks !!
