Question

Formula of diagonal of Cube & Cuboid.

Answer 1

Answer:

Step-by-step explanation:

Volume of a cube: V = a. ...

Surface area of a cube: the area of each face (a x a) times 6 faces. S = 6a. ...

Face diagonal of a cube: By the pythagorean theorem we know that. f2 = a2 + a. Then f2 = 2a. ...

Diagonal of the solid cube: Again, by the pythagorean theorem we know that. d2 = a2 + f.(for a cube)

If l, b and h denote the length, breadth and height respectively of the cuboid then the length of its diagonal d is given by the formula d = √(l^2+b^2+h^2).(for a cuboid)
