Area of 1 = Length × width

Length = 11
Width = 11

11 · 11 = 121

There are 6 squares.

Multiply 121 by 6 to get the total

121 · 6 = 726

Surface Area = 726 cm²

Hello!

To find the surface area of a cube you use the equation

$6 a^{2}$

a is a side length

Put in the values you know

$6 * 11^{2}$

Square the number

6 * 121 = 726

The answer is $726cm^{2}$

Hope this helps!

1. The x-intercepts are x = 0 and x = 6. You can find these by looking for where the line crosses the x-axis. You can see here that it does so at 0 and 6.

2. The maximum value for this function is looking for the f(x) value at the highest point. In this case, you will see that f(x) at the highest point is 120. This happens at x = 3. Once again, this can be found just by looking for the highest point on the graph.

3. Since that is the absolute highest point, it is also the point where is goes from increasing to decreasing. As a result, we know the increasing interval is x<120 and the decreasing interval is x > 120.

4. Finally, the average rate of change between 3 and 5 is -30. You can find this by determining the amount of change in f(x) and dividing it by the amount of change in x. The basic formula is below.

$\frac{new f(x) - old f(x)}{new x - old x}$
