81 cm²

Solution :

Given : Volume = 729 cm³

To find : Base Area = ?

Here ,

It is given that the volume of the cube is 729 cm³ .

Thus ,

=> Volume = 729

{ Volume of cube = Side³ }

=> Side³ = 729

=> Side³ = 9³

=> Side = 9

Now ,

The Base Area the cube will be given as ;

=> Base Area = Side²

=> Base Area = 9²

=> Bade Area = 81 cm²

Hence ,

Area of the base of the given cube is 81 cm² .
