Question

What is the surface area to volume ratio for a cube that measures 8 cm on each side?

Answer 1

`0,75 "cm"^-1`

Explanation:

First, you have to calculate the surface of your cube.

Surface of one face : `"s" = 8*8=64 "cm"^2`
Total surface (surface of one side multiplied by the number of
sides) : `"S" =64*6=384 "cm"^2`

Second, calculate the volume

`"V" = "s"*"hauteur" = 64*8 = 512 "cm"^3`

Finally, the surface to volume ratio R :

`"R" ="S"/"V"= 384/512 = 0,75 "cm"^-1`
