A regular octagon has all its eight sides congruent. The line segments joining each of the vertices of a regular octagon to its center are called the radii of the octagon. These 8 radii divide a regular octagon into 8 congruent isosceles triangles. Area of each isosceles triangle is
,
where a is length of the side of the octagon and 
is the angle between two radii of the octagon.
In regular octagon
.
Then the area of regular octagon is
sq. m.

The volume of your box is 19 times 17 times 6. You will get 1938 in. cubed.
TT is your rational number because either way it’s a TT or A
Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20
---- ------
4 4
n = 5
multiply the whole number with the denominator then add the numerator over the denominator then find the common multiple.
