Find the surface area of a cube having an edge length of 4 feet each

96 square feet

Step-by-step explanation: Surface area is the sum of the areas of all of the faces of a three dimensional figure. If we wanted to find the surface area of the cube, notice that each face of a cube has the same area. We can simply find the area of 1 face of a cube and multiply it by the number of faces. To find the area of 1 face of a cube, we can use the formula for the area of a square.

Area =

Since the length of the side is 4 ft. we have as followed.

(4 ft.)²

16 ft.²

Now, since there are six sides to a cube we have to multiply by 6.

6 (16ft.²)

96 ft.²

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
