determine the length of one edge of a cube that has a surface area of 864 square inches.
The surface area of a cube with an edge length of 5.5 yards is: 181.5 square yards.
216 square inch total surface area, divide that by 6 to have the area of each square face, 36 square inch. The square root of that is the length of one side, 6 inches.

determine the length of one edge of a cube that has a surface area of 864 square inches.
The surface area of a cube with an edge length of 5 inches is 150 square inches.
The surface area of a cube with an edge length of 5.5 yards is: 181.5 square yards.
The edge length is 7.35 inches.
Area(10) = 600 and Area(2) = 24.
ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!

216 square inch total surface area, divide that by 6 to have the area of each square face, 36 square inch. The square root of that is the length of one side, 6 inches.
First, get the length of one side of the cube. Then, square it and multiply that number by 6. For example, the length of one side is 3. Square it (9) and multiply 9 by 6, which is 54. So, the surface area of that cube is 54.
If the surface area of a cube is 294cm^2, the length of one side is equal to the square root of (294/4), which is approximately 8.57cm.
