Answer:
Step-by-step explanation:
Volume of 1 cube = 6*6*6 = 216cm
Volume of 2 cube = 8*8*8 = 512 cm
Volume of 3 cube = 10*10*10 = 1000cm
Sum of volume of these 3 cubes = volume of newly formed cube
Therefore 216+512+1000 = 1728cm
Edges = 12 cm.(cube of 1728 )
TSA of cube = 6* 12*12 = 6*144 = 864cmsq
Hope this helps you
