Hello!!
So diagonal of cube is side√3
so diagonal is 9√3
hence
9√3 = side√3
side = 9 √3 /√3
side = 9
Hence volume of cube is side^3
hence volume = 9 X 9 X 9
volume = 729
Hence you answer is 729
HOPE THAT HELPS YOU!!!

Answer:
The diagonal of a cube = a( root 3) where a is the side............ 1
Diagonal = 9 (root 3)................. 2
From 1 and 2,
9(root 3) = a (root 3)
On cancelling (root 3) from both sides,
9 = a i.e., 9 cm is the side of the diagonal.
TSA = 6(a^2)
=6(9*9)
=6*81
=486 cm^2
LSA = 4(a^2)
= 4 (9*9)
= 4*81
=324 cm^2
