Explanation:
Surface area is 54cm²
, volume is 27cm³
and surface area-to-volume ratio is 2
Explanation:
If s is the side of a cube, then its surface area is 6s²
and its volume is s³
Hence, if the sides of a cube are 3 inches long
its surface area is
6×3²
=6×9
=54cm²
,
its volume is 3³=27cm³
and surface area-to-volume ratio is
54/27=2
