(B) The formula for the diagonal of a cube with side length $a$ is given by $d = a\sqrt{3}$.Given the diagonal $d = \sqrt{300} 	ext{ cm}$.So,$a\sqrt{3} = \sqrt{300}$.Squaring both sides,we get $3a^2 = 300$.Dividing by $3$,we find $a^2 = 100$,which implies $a = 10 	ext{ cm}$.The total surface area of a cube is given by $6a^2$.Substituting the value of $a$,we get $6 	imes (10)^2 = 6 	imes 100 = 600 	ext{ cm}^2$.

The diagonal of a cubical box is $\sqrt{300} \text{ cm}$. Find out the surface area.
