If the surface area of a cube is 384, what is the length of one of the sides of<br> the cube?

Setler79 [48]

Answer:

S = 8

Each side of a face is 8 units.

Step-by-step explanation:

The surface area of the cube is 384 units.

One face of the cube has an area of s^2

A cube has 6 faces

6s^2 = 384 Divide by 6

s^2 = 384 / 6

s^2 = 64 Take the square root of both sides

sqrt(s^2) = sqrt(64)

s = 8

$\begin{gathered} A=l\times b \\ A=42\times25.5 \\ A=1071ft^2 \end{gathered}$

Step 2: Find the cost of wallpaper per square foot

$=\frac{total\text{ cost of wallpaper}}{Area\text{ of the wall}}$ $\begin{gathered} =\frac{771.12}{1071} \\ =0.72\text{ dollars} \end{gathered}$

The correct answer is B: $0.72
