Question

Find the of each side of a cube if its volume is 512 cm square

Answer 1

Question should be:

• Find the of each side of a cube if its volume is 512 cm cube.

ANSWER:

• Each side of cube = 8 cm

GIVEN:

• Volume of cube = 512 cm³

TO FIND:

• Side of a cube.

SOLUTION:

Formula:

Volume of cube = (Edge)³

Here :

Volume of cube = 512 cm³

=> (Side)³ = 512 cm³

=> (Side)³ = (8)³

Exponents are same then :

=> Side = 8 cm

Each side of cube = 8 cm.

NOTE:

Some important formulas:

Volume of cube = (Edge)³

Volume of Cuboid = (Length)(Breadth)(Height)

Curved surface area of Cylinder = 2πrh

Total Surface area of sphere = 4πr²

Curved surface area of hemisphere = 2πr²

Total surface area of hemisphere = 3πr²

Where:

=> r = radius.

=> h = height
