.
Side of cube 1=s
Side of cube 2=3s
.
Surface area cube 1=6s^2
Surface area cube 2=6(3s)^2=6(9s^2)=9(6s^2)
Ratio Surface Area cube 1:Surface Area cube 2=1:9
.
Volume cube 1=s^3
Volume cube 2=(3s)^3=27s^3
Ratio volume cube 1:Volume cube 2=1:27

Hi dear
If the ratio of their lenght is 1:3,
Then,express the ratio of their lenght as fraction

i.e
Then;

=1/9
=1:9
Also.

=1/27
=1:27
The ratio of their area is 1:9
and the ratio of their volume is 1:27
HOPE THIS HELPS;
Best regards,
Timnewman
