Question

# Find out the side of cube if the complete surface area is given to be 346.56 cm^{2}.

- 6.7
- 7.6
- 5.6
- 8.6

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

where a is the side of cube

## The correct answer is: 7.6

- Step 1:We have given the total surface area of the cube.

Area = 346.56 cm^{2}

- Step 2: We know that

Surface Area = 6a^{2}

346.56 = 6a^{2}

^{· }Step 3: For finding the side firstly divide both sides if equation by 6

- Step 4:- Taking square root of both sides we get,

^{· }Step 5: Therefore, the length of side of the given cube is 7.6 cm^{2}.
- Therefore, the correct answer is option B) 7.6 cm.

^{2}

^{· }Step 3: For finding the side firstly divide both sides if equation by 6^{· }Step 5: Therefore, the length of side of the given cube is 7.6 cm^{2}.- Therefore, the correct answer is option B) 7.6 cm.
