Question

how do you find the surface area to volume ratio?

Answer 1

if its easier to just help with the question itself than i can post the numbers on here.

Answer 2

its a cube

Answer 3

ok, what is the length of the leg?

Answer 4

surface are- 1.5 volume- 2.5
surface area- 6 volume-1
surface area -25 volume -27
surface area- 54 volumee - 27

Answer 5

oh and the lengths are
.5
1
2
3

Answer 6

no sorry i should have explained it better the length of each cube is
cube 1 each side is .5
cube 2 each side is 1
etc.

Answer 7

ok, I am sorry, so, just find out the general form, and then replace the length of the leg, right? now, pick x = y =z = 1

Answer 8

to be completly honest i am horrible at math it is my worst subject so youre going to have to eli5

Answer 9

sorry "reddit talk" explain like im 5

Answer 10

yea i get that

Answer 11

you have the formula to get the volume of a cube is V = x ^3 got it?

Answer 12

i already have the volume

Answer 13

i need the surface area to volume ratio.

Answer 14

so, the ratio of a surface to a volume is \(\dfrac{surface}{volume}\) and you have surface is 6x^2, volume is x^3, therefore, the ratio is \(\dfrac{6x^2}{x^3}= \dfrac{6}{x}\)That is general form
now, particular solution: if x = 0.5 , then ratio = \(\dfrac{6}{0.5} = ..\) you can calculate it, right?
if x =1 , then ratio = \(\dfrac{6}{1}=6\)
if x =2......
if x = 3,........

Answer 15

where did the 6 come from? are those the sides?

Answer 16

surface of a cube = 6 sides of the cube, each side have area = x^2
