Question

the total surface of a cube is s square units and length of diagonal d units then the relation between s and d is?​

Answer 1

s = 6 a^2 (where a is the length of an edge of a cube).

d = √3 a (where a is the length of an edge of a cube)

s/d = 6a^2/√3a

or, s/d = 6a/√3

or, s/d = (6a×√3)/3

or, s/d = 6√3a/3

or, s/d = 2√3a

From here you will be able to say that s = 2d^2 (where "s" is the total surface area of the cube and "d" is the diagonal of the cube.)

Answer 2

Answer:

S = 2d²

Step-by-step explanation:

let cub side length = a

S = 6a²

d² = 3a²

S = 2d²
