Question

Find the volume of cube whose diagonal length is 34.6 cm

Answer 1

hii Frs.

using the formula .

$v= a 3$
$d = \sqrt{3 \: } \: a$
Solving for V

$d = \sqrt{3} \frac{d {}^{3} }{9} = \sqrt{3} . \frac{34.6 {}^{3} }{9}$
$= 7971.61681cm {}^{3}$

Answer 2

hii Frs.

using the formula .

v= a 3v=a3

d = \sqrt{3 \: } \: ad=

a

Solving for V

d = \sqrt{3} \frac{d {}^{3} }{9} = \sqrt{3} . \frac{34.6 {}^{3} }{9}d=
