If the length of a cube is 6 inches, what is the surface area?

Step-by-step explanation:

We can find the surface area of an object by finding the area of all its sides and adding them up.

We know that a cube has 6 identical sides. Therefore, we can just find one side and multiply by 6.

A cube is made up of 6 squares. We can find the area of this square by squaring the length (multiplying it by itself).

Since the length is 6, that means the area of one side of the cube must be

Since there are 6 identical sides, the total surface area must be:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
