Question

if the length of a diagonal of cube is 8 under root 3 cm find its surface​

Answer 1

Answer:

Step-by-step explanation:

given,

diagonal=√3^a

8√3 =√3a

a=8cm.

now,

surface area of cube=6a²

=6x (8)²

=384cm²..

Answer 2

length of the diagonal of cube = √3 a

now, √3 a = 8√3

a = 8 cm

hence, surface area of the cube = 6a² = 6×64 = 384 cm²
