Question

If the length of the diagonal
of a cube is 12v3 cm then the
surface area of the cube?​

Answer 1

Answer:

864 cm²

Step-by-step explanation:

Let the side of the cube be 12 cm

Length Of The Diagonal = $\sqrt{3}$ a

According to the question,

length of diagonal = 12$\sqrt{3}$ cm

Therefore, $\sqrt{3}$ a = 12$\sqrt{3}$ cm

                        a = 12 cm

Therefore, Total Surface Area of the cube = 6 a²

                                                                      = (6×12×12)cm²

                                                                      = 864 cm²

The Total Surface Area of the cube is 864 cm².
