\frac{n}{3} +6 - 7 = 4
Subtract 6 from each side of the equation

\frac{n}{3} -7 = -2

Now add 7 to both sides of the equation.

\frac{n}{3} = 5

Finally multiply by 3 on both sides to undo the division

n= 15

Check
15/3 + 6 -7 = 4
5     + 6  -7 = 4
     11-   7 = 4
        4    =   4

The formula for the surface area of a right rectangular prism is A  2lw  2hw  2lh, where l, w, and h represent the length, wi
Thepotemich [5.8K]

Answer:

The term 2lw is independent of the height

Step-by-step explanation:

This formula is usually obtained reasoning like this: the rectangular prism has 6 faces, thus the surface area is the sum of the areas of these faces.

2 faces are l×w rectangles, so their area is lw+lw=2lw. Note that we are not using the height to compute the area, then this is the independent term.

The 4 remaining rectangles involve the height as one of their dimensions, so their areas (2hw+2lh) depend on the height.
