Answered by mysticd

let the side of the cube = s
volume = s³
given volume =3√3 a³
s³=(√3*3*3 )*a³
s³= (√3* a)³
s= √3 *a
total surface area of the cube = 6*(side)²
= 6*(√3 *a)²
= 6*3*a²
=18a² square units

wilsonnisha: if the volume of cube is given as 3root 3 a^3, which is actually root 3a*root3a*root3a.......

wilsonnisha: which means one side of the original cube is root 3 a,

wilsonnisha: so,tsa of cube, ie, 6a^2 equals 6*(root3a)^2 = 6*3a^2=18a^2

mysticd: i did the same
