The length of a diagonal of a cube is $5 \sqrt{3} cm$. The volume and the surface area of the cube are respectively:
Answer & explanation
Correct answer: option 2
Diagonal of cube = √3 × side
√3 × side = 5√3
side = 5
Volume of cube = ( side )³ = ( 5 )³ = 125
Surface are of cube = 6( side )²
= 6( 5 )²
= 150
The correct answer is Option (2) → $125 cm^3$ and $150 cm^2$
