first find the total surface areas of 3 cubes
216;384;600 respectively
now add them 3
1200
now this is total surface of larger cube
therefore 6a^2=1200
side of larger cube is 14.15

Volume of cube= volume of new cube
=6+8+10=a
Squaring both sides
36+64+100=a*
200=a*
a=100root 2
=6+8+10=a
Squaring both sides
36+64+100=a*
200=a*
a=100root 2
