Question

If the length of the diagonal of a cube is `5sqrt(3)` cm, find the total surface area.

Length of the diagonal of the cube = `square`

So, `square` = `5sqrt(3)`

⇒ Side = `square`

Total surface area of cube = `square`

= `square` × `square` × `square`

= `square` cm²

 Hence, the total surface area is `square`.

Answer 1

Length of the diagonal of the cube = `bb(5sqrt(3) cm)` 

So, `bb("Side" xx sqrt(3))` = `5sqrt(3)`

⇒ Side = 5

Total surface area of cube = 6 × Side²

= 6 × 5 × 5

= 150 cm²

 Hence, the total surface area is 150 m².
