Answer 1

Answer:

Length of diagonal of cube =

$\sqrt{3} a$

Answer 2

SOLUTION

TO DETERMINE

The length of diagonals of a cube of side a cm

EVALUATION

We know that cube is a three dimensional solid object with six square faces and all sides are of equal length

Here it is given that the side of the cube = a cm

Hence the required length of diagonal

$\sf{ = \sqrt{ {a}^{2} + {a}^{2} + {a}^{2} } \: \: \: cm }$

$\sf{ = \sqrt{3{a}^{2} } \: \: \: cm }$

$\sf{ =a \sqrt{3 } \: \: \: cm }$
