Answer:
option B. square root of 3
Step-by-step explanation:
In the figure attached the length of one side of the cube is 1 cm.
In the triangle ABC, Side AB = 1 cm
Since side BC is the diagonal of 1 base of the given cube.
Therefore, mBC = [tex]\sqrt{1+1}=\sqrt{2}[/tex] cm
Now we have to calculate the length of diagonal AC.
AC = [tex]\sqrt{AB^{2}+BC^{2}}[/tex]
AC = [tex]\sqrt{1+2}=\sqrt{3}[/tex]
Therefore, option B. square root of 3 will the length of diagonal of the cube.
