Question

Edge of a metal cube is 3 cm. Find the total surface area of the cube.

Answer 1

Given that,

Edge of a metal cube is 3 cm,

Now we know that,

Total surface area of a cube is 6 × (edge)²

Then,

The total surface area of the cube is 6 × (3)² cm²

= 6 × 9

= 54 cm²

The total surface area of the metal cube with edge 3 cm is 54 cm²_.
