Can you calculate either the surface area or the volume of this cube? Which do you need help with?

anonymous · Answer

A cube has all equal sides. It means that the length, width and height is 2. 
Volume=2*2*2
Surface area= 3[2(2*2)]
The volume would be 8 surface area would be 24.
A ratio of surface area to volume would be 24:8.
Simplified 3:8 (when divided by 8).

why 3:8?
wouldn't 
24:8 be 
24/8:8/8
3:1

anonymous · Answer

You're correct up to 24:8
however, that simplifies to 3:1
Divide both 24 and 8 by 8
you get 3:1
