Question

The volume of a cube whose diagonals is 3.6 m is

Answer 1

so
volume of a cube of diagonal =3.6 m
$\sqrt{3a}$
=3.6
so
36/10
12 / 5
$\sqrt{3a = 12by \: 5}$
12/ 5 is a out of root
so by apply these formula u will get the value of a ...

Answer 2

Diagonal of a cube with side s = √3 s.

Now, d = √3 s

From this, s = d/√3 .

Volume = s³ = d³/3√3 .

Given, Value of d = 3.6m .

Now, Volume = 46.656/3√3 = 26.93 m3 .
