Question

A diagonal of a cube measures 7 root 3cm.its volume is

Answer 1

Step-by-step explanation:

For a cube ,

Diagonal = a/√3

a/√3 = 7√3 cm

a = 7*3 = 21 cm

Volume of Cube = a³ = 21³ = 9261 cm³

Answer 2

Answer:

Let side of a cube = a units

Diagonal of a cube (d)=7√3 units

=> √3a =7√3

Divide each term by √3 , we get

=> a = 7 units

Now,

Volume of the cube (V)=a³

= (7 unit )³

= 343 cubic units
