The length of a diagonal of a cube is $5 \sqrt{3} cm$. The volume and the surface area of the cube are respectively: |
$150 cm^3$ and $125 cm^2$ $125 cm^3$ and $150 cm^2$ $125 \sqrt{3} cm^3$ and $180 cm^2$ $375 \sqrt{3} cm^3$ and $150 cm^2$ |
$125 cm^3$ and $150 cm^2$ |
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 $150 cm^2$ |
