Check the picture below.

so let's simply get the area of each of those six rectangles and sum them up.

$\stackrel{\textit{\large Areas}}{\stackrel{\textit{left and right}}{2(2\cdot 4)}+\stackrel{\textit{front and back}}{2(5\cdot 2)}+\stackrel{\textit{top and bottom}}{2(5\cdot 4)}}\implies 16+20+40\implies 76$

A jar contains 1,200 M&M's and everyday your family eats 1/5th of the candies. After how many days will there be 314 M&M

mrs_skeptik [129]

The equation is 314 = 1,200 - 240x

1,200 is the number of M&M's it starts with
The problem said the family eats 1/5th of the candy every day
1/5 of 1,200 is 240
It is a -240 because the amount of m&m's is getting fewer each day
The x stands for the number of days

Sorry but I'm not sure if I could answer your problem exactly
The answer is 3.69 days
Because there isn't an exact day that there would exactly 314 M&M's left
