Here your answer✍️
Volume of Two cubes=1:27
Volume of cube=(edge)³
Edge of first Cube
a³=1
a=³√1
a=1
Edge of second cube
a³=27
a=³√27
a=3
Now edge Ratio=1:3
Surface Area=6a²
Surface Area of first Cube
=6×1²
Surface Area of second cube
=6×3²
Ratio of surface area=1:9
Volume of Two cubes=1:27
Volume of cube=(edge)³
Edge of first Cube
a³=1
a=³√1
a=1
Edge of second cube
a³=27
a=³√27
a=3
Now edge Ratio=1:3
Surface Area=6a²
Surface Area of first Cube
=6×1²
Surface Area of second cube
=6×3²
Ratio of surface area=1:9
