Question

the digonal of a cube isroot 12. find its volume

Answer 1

Diagonal of cube = √12
 Let its side be a

then, √3a = √12
             a = √12/√3
             a = 2√3/√3
        so, a = 2 

so, Volume of cube = (2)³ = 8 cubic units.

Answer 2

Answer:

let the length of side be a cm

diagonal = √12

=> √3 a = 2√3

=> a = 2 cm

now , volume of cube = a³. = 2³= 8 cm³

volume of the cube is 8 cm³.
