Question

Area of total surface of a cube is S square units and length of diagonal is D units, then
(A) 2D2= S´ (B) D2= S (C) 2S2= D (D) S2= D​

Answer 1

Answer:

Step-by-step explanation:

let cub side length = a

S = 6a²

d² = 3a²

S = 2d²

Answer 2

Answer:

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