Question

The length of the diagonal of a cube is 8√3 cm .what is its total surface area?

Answer 1

Root(3)side=diagonal of cube

Thus solving given data by above formula,

               Side=8cm

Total surface area=6(side)²

                             =6(8)²

                             =6*64=384cm²

Answer 2

Answer:

Step-by-step explanation:

given,

diagonal=√3^a

8√3 =√3a

a=8cm.

now,

surface area of cube=6a²

=6x (8)²

=384cm²..
