Jason is making sand art. He wants to fill a rectangular patch 6 inches by 7 inches with blue sand, and a square path 5 inches by 5 inches with red sand. If it takes 3 grams of sand to fill one square inch, how many grams of sand does Jason need?
First find the area of the first patch: 6 inches * 7 inches =

<output>42</output>
42 inches.
Then find the area of the second patch: 5 inches * 5 inches = 
<gadget id="calculator">5*5</gadget>
<output>25</output>
25 inches.
Then add those two amounts to find the total area Jason needs to cover: 42 inches + 25 inches = 
<gadget id="calculator">42+25</gadget>
<output>67</output>
67 inches.
Then multiply that area by the number of grams per square inch to find the total amount of sand needed: 67 inches * 3 grams/square inch = 
<gadget id="calculator">67*3</gadget>
<output>201</output>
201 grams.
