Explanation:
I prefer to make a two way table for problems like this. Such diagrams make it fairly clear why multiplication is used when it comes to probability and counting problems.
Check out the diagram below.
The table has 6 rows and 2 columns.
The 6 rows represents the outcomes 1 through 6 on the number cube.
The 2 columns represent the outcome of heads (H) vs tails (T)
Inside the 6*2 = 12 inner cells, we'll have each outcome.
For example, the upper left corner has H1 to mean "flipped heads and got a 1 on the number cube". The next cell over is T1 to mean "tails on the coin, 1 on the number cube". The rest of the table is filled out in this manner.

Step-by-step explanation:
<u><em>The correct question is</em></u>
Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?
we know that
The area of a rectangle is equal to
where
L is the length
W is the width
we have
substitute
solve for L
