The surface area of a cube is 294 square feet. what is the length (in feet) of each edge of the cube? a. -7 feet b. 7 feet c. 49 feet d. 64 feet

Answer  7 feet

the cube has 6 faces

294/6=49

1 face =49

surface=l*w

49=l*w   (I and w measure the same,so lets call each the same letter=e

49=e*e

49=e^

do square root of both sides

Square root of 49= square root of e ^

7=e
