A cube has a lateral area of 676 square feet. What is the side length of the cube?
Answer
A
6 point 5 feet
B
13 feet
C
4 point 3 feet
D
10 point 6 feet
Explanation
A cube has four side faces, so its lateral area is 4s², where s is the side length. Set 4s² = 676, giving s² = 169 and s = 13 feet. Therefore, the correct choice is 13 feet.
