$\"\"$

A $\"\"$ m log is cut at $\"\"$ - meter intervals.

Its cross sectional areas $\"\"$ at a distance $\"\"$ from the end of the log are listed in the table.

Find the volume of the log by using midpoint rule with $\"\"$ .

Width of the interval $\"\"$ .

Mid points are $\"\"$ and $\"\"$ .

Mid point Rule :

Volmue of the log is $\"\"$ .

Substitute $\"\"$ and corresponding values from the table in above expression.
