Question
calculate the surface area of a cube with a side of 4 mm
- 72 mm2
- 96 mm2
- 64 mm2
- 56 mm2
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: 96 mm2
- Step 1:We have given the length of the side of the cube.
Side = 4 mm
- Step 2: Find the square of the length of the side of the cube.
(Side)2= (4)2= 16 mm2
- Step 3: For total surface area, find out the product of the square of side length by 6.
Surface area = 6(side)2
= 6(16)
= 96 mm2
- Step 4: Therefore, the surface area of the given cube is 96 mm2.
- Therefore, the correct answer is option B) 96 mm2.
