Find out the side of cube if the complete surface area is given to be 346.56 cm².

The correct answer is: 7.6

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

Area = 346.56 cm²

• Step 2: We know that

Surface Area = 6a²
                                                                               346.56 = 6a²

• ^·          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 cm².
  • Therefore, the correct answer is option B) 7.6 cm.
