Question

If the area of 1 face is 81 how much is the surface area of the whole cube?

  1. 486
  2. 9
  3. 81
  4. 324

Hint:

Total Surface Area of Cube: The total surface area of a cube refers to the total area covered by all six faces of a cube. To calculate the surface of a cube, we find the sum of the areas of these 6 faces.
Surface Area = 6a2
= 6 (area of face)
where a is the side of cube

The correct answer is: 486


    • Step 1:We have given area of one face of the cube.
    Area of face = 81
    • Step 2: For total surface area, find out the product of the square of side length by 6.
    Surface area =  6 (area of face)

                          =  6 (81)

                          =   486

    • Step 4: Therefore, the surface of the given cube is 486.
    • Therefore, the correct answer is option A) 486 .
