Answer:
Volume
=
512
cubic feet
Explanation:
A cube has
6
faces all with equal area.
If the total surface area of the cube is
384
sq.ft.
then each face has an area of
384
÷
6
=
64
sq.ft.
Each face of a cube is a square and if we denote the length of an edge as
E
then the area of a face (in this case
64
sq.ft.) is equal to
E
2
XXX
E
2
=
64
sq.ft.
XXX
→
E
=
8
sq.ft.
The volume of a cube with edges of length
E
is
E
3
In this case
Volume
=
E
3
=
8
3
=
512
sq.ft.

The correct system of equations for this is:
x - y = 6
3x + 4y = 4
The easiest way to find answer in a multiple choice problem like this is by looking at the answer to the system of equations. The solution set to a system is always where the two lines cross. Here, we see that cross at the point (4, -2). This means that if we put 4 in for x and - 2 in for y, it will make both equations true. The only example of both being true is the set of equations listed above. Below is the work for what happens when we put those values in.
First Equation
x - y = 6
(4) - (-2) = 6
4 + 2 = 6
6 = 6 (TRUE)
Second Equation
3x + 4y = 4
3(4) + 4(-2) = 4
12 - 8 = 4
4 = 4 (TRUE)
Since both are true in this version and none of the other systems, this must be the system graphed above.
