Nathan wants to line the inside of a box with velvet. The box has two long sides that measure 8 inches by 6 inches, two short sides that measure 5 inches by six inches and a top and a bottom that each measure 40 square inches. How many square inches of velvet does Nathan need?
First find the area of each long side by multiplying the length and width: 8 inches * 6 inches = 
<gadget id="calculator">8*6</gadget>
<output>48</output>
48 square inches.
Then do the same thing for each short side: 5 inches * 6 inches = 
<gadget id="calculator">5*6</gadget>
<output>30</output>
30 square inches.
Now add the area of one long side, one short side, and one top/bottom together: 48 square inches + 30 square inches + 40 square inches = 
<gadget id="calculator">48+30+40</gadget>
<output>118</output>
118 square inches.
Now double that quantity because there are two of each kind of side: 118 square inches * 2 = 
<gadget id="calculator">118*2</gadget>
<output>236</output>
236 square inches.
