A) 300
B) 600
C) 1200
D) 2400
Correct Answer: B
Solution :
If each side of the cube \[=a\text{ }cm,\]then length of a diagonal \[=a\text{ }\sqrt{3}cm,\] surface area\[=6{{a}^{2}}\]. Since \[a\sqrt{3}=\sqrt{300},\]therefore\[a=10,\]and surface area \[=6{{a}^{2}}=600.\]You need to login to perform this action.
