If the longest diagonal of a cube is $6\sqrt{3}$ cm, then its volume and surface area are _____ and _____ respectively. |
$216 cm^3$ and $210 cm^2$ $216 cm^3$ and $216 cm^2$ $216 cm^3$ and $226 cm^2$ $226 cm^3$ and $226 cm^2$ |
$216 cm^3$ and $216 cm^2$ |
Longest Diagonal of a cube = a√3 = 6√3 ⇒ a = 6 cm ⇒ Surface area of cube = 6 × a2 = 6 × 62 ∴ 6 × 36 = 216 cm2 its volume a3 = 63 = 216cm3 |
