Question

Find the surface area and diagonal of a cube whose edge is 11 cm

Answer 1

HEY DEAR ... ✌️

______________________


Edge of the cube=11cm
Lateral surface area of cube=4a^2
=4*11*11
=484cm^2

HOPE , IT HELPS ...

Answer 2

Here is given a cube with an edge of 11cm.

The total surface area of the cube will be 6a² where a is the side of the cube.

So, TSA = 6(11)² = 6*121

              = 726cm²

Curved or Lateral surface area of the cube will be 4a² where a is the length of the side of the cube

So, LSA= 4(11)² = 4*121

             = 484 cm²

Diagonal of the cube will be (√3)(a) where a is the side of the cube

So, D=11√3 cm.

Thanks!!!
