Count the number of units for the area's width, length, and height. Then, use the appropriate formula for the shape and multiple the number of units by their value.
Draw the shape on the paper. Cut out the shape, and weigh it. Compare the result to the weight of
a rectangle with a known number of squares of graphpaper.
The point of graph paper is to make it easier to see the area of a shape. Each box on the paper represents one unit of volume, so if you have a shape that is made up of 10 boxes, you know its area is 10.
