Question

Find the maximum length of the rod that can be put inside the cube of each side 5cm

Answer 1

Answer:

7.1cm

Step-by-step explanation:

A perfect cube with each side as 5cm can have a rod of max length equal to the diagonal side length of the cube.

So as per Pythagoras theorem:

a^2 + b^2 = h^2

a = b = 5cm

so h^2 = 50

h =

$\sqrt{50}$

h = 5√2 = 5 x 1.414 = 7.070cm ~ 7.1cm
