If the length of diagonal of a cube is $8\sqrt{3}$ cm then what is its surface area?

164 cm2 64 cm2 384 cm2 204 cm2

384 cm2

We know that, Diagonal of cube = \(\sqrt {3}\) × Side of cube Surface area of cube = 6a2  Diagonal of cube = Side of cube \(\sqrt {3}\) = 8\(\sqrt {3}\) = Side of cube = 8  Now, surface area of cube = 6(8)2 = 384 cm2.
