Surface area of a cube with the length of each edge equal to x+1

AI Thread Summary
To find the surface area of a cube with edge length x+1, first recognize that a cube has six square faces. The area of each face can be calculated using the formula for the area of a square, which is side length squared. Therefore, the surface area of the cube is 6 times the area of one face, resulting in the formula 6 * (x+1)². Understanding the shape of each face and the calculation method is essential for determining the total surface area. The discussion emphasizes the importance of grasping the concepts rather than simply receiving answers.

How many sides does a cube have? What is the surface area of each side?
 
a cube has 6 sides and i don't the the surface area of each side i only know that each edge length is x+1 can some one help
 
i mean i don't know the surface area of each side

What sort of shape is each side, and how do you calculate the area of that shape?
 
Uh, we try not to just hand out answers here...
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
