Question

The surface area of a cube is found using the SA=6s^2, where s is the side length. If the surface area of a cube is 294 square meters, what is the length of the cube, in meters? A. 7 B. 24.5 C. 42 D. 49

Answer 1

6s^2 = 294
s^2 = 49
s = 7
The answer is 7 meters (A)

Answer 2

6s² = 294
s² = 294/6
s² = 49
s = √49
s = 7 meters
