Question

find the total surface area and its diagonal of cube whose volume is 343 CM^3

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :

Volume of cube = 343 cm³

We have to find side.

Let the side be a .

A. T. Q

( side )³ = 343

a³ = 343

$a = \sqrt[3]{343}$

$a = 7$


Side of cube = 7 cm

__________________

Total surface area of cube :

= 6 × ( side)²

= 6a²

= 6 × (7)²

= 6 × 49

= 294 cm²

__________________________

Diagonal of cube :

$= \sqrt{3} \times side$

$= \sqrt{3} a$


$= \sqrt{3} \times 7$


$7 \sqrt{3} \: \: cm$
