Surface area is the total area of the surface. A cube has 6 surface, and each surface is the same. Each surface is a 11 by 11 square. Therefore there will be 6 11in. x 11in. surfaces. The math would be 11x11x6 =726.

Answer:

726 in²

Step-by-step explanation:

The surface area of a cube is the area of each side of the cube multiplied by 6 (since the cube has 6 sides).

To know what is the area of each side, the formula is A= l² where l is the length. Therefore we would have that the area is 11²=121.

Now we are going to multiply this number by 6 to find the surface area, SA = 121 x 6 = 726 in²

Explanation:

Graphically, where the line crosses the x -axis, is called a zero, or root. Algebraically, a zero is an x value at which the function of x is equal to 0 . Linear functions can have none, one, or infinitely many zeros.
