Mary wants to wrap a shirt she bought her son for his birthday. She places it in a box that measures 12 inches long, 8 inches wide, and 6 inches tall. what is the surface area of the box that Mary wants to wrap?
A. 26 inches squared
B. 120 inches squared
C. 216 inches squared
D. 432 inches squared

D, or 432 Inches Squared

Step-by-step explanation:

First we have to find each side

Front = 6 x 12, 72

Side = 6 x 8, 48

Bottom/Top = 12 x 8, 96

Next we multiply each side by 2, since there is 2 sides for each respective surface.

72 x 2 = 144

48 x 2 = 96

96 x 2 = 192

Lastly, we add them all together, since we are finding surface area!

144 + 96 + 192 = 432

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
