Question

volume of cube is 729 metre cube the total surface area of cube is

Answer 1

vol of cume=s^3
$\sqrt[3]{729 } = 9$
TSA of cube =6l^2
=6*81=486

Answer 2

Hey


Given that :-
Volume of cube = 729 m³
We know that ,
Volume of cube = ( a ) ³

A / q ,
( a ) ³ = 729
=> ( a ) ³ = ( 9 ) ³
=> a = 9

So , side of cube = 9 cm .

Now ,
total surface area = 6a²
= 6( 9 ) ²
= 6 * 81
= 486 m²

thanks :)
