Term 1 of 72
If my pace is 12.4 paces/chain, how many paces do I need to cover a distance of 5.32 chains?
(12.4)(5.32) = 65.96 or 66.0 paces
145/13.1 = 11.07 chains
True because a cord must equal to 128 cu ft
Formula dib = dob - double bark thickness
17.5 - .4 = 17.1"
Term 2 of 72
A ring count at breast height reveals 15 rings (a ring consists of both springwood and
summerwood). How old is the tree?
20 years + 1 year if pine or 3 years if hardwood
15 years + 3 years if pine or 5 years if hardwood
10 years + 2 years if pine or 4 years if hardwood
25 years + 6 years if pine or 2 years if hardwood
Term 3 of 72
Compute cubic foot volume of a 8-ft. log, given that diameters at both ends are 14" and 15",
respectively.
8.00 cu ft volume
10.50 cu ft volume
11.25 cu ft volume
9.18 cu ft volume
,Term 4 of 72
Convert 450 sq.in. = ________ sq.ft.
Formula = Divide it by 144
450in/144 = 3.125 sq ft
Formula dib = dob - double bark thickness
17.5 - .4 = 17.1"
5.476*66= 361.42 feet
Formula = divide the area value by 43560
78124/43560 = 1.8 ac
Term 5 of 72
Define Girard form class.
Pine: 1 MBF = 16,000 lbs, 1 cord = 5,400lbs
Hardwood: 1 MBF = 19,000 lbs, 1 cord = 5,700lbs
Girard form class = 100 (dib@17.3' / dbh)
17.3' = 16' log + 1' stump + 0.3' trim allowance
Reason: (DBH) (FC) = scaling diameter of the first log
Formula for error % is 100 (measured distance - paced distance)/ measured distance
100* (26.453 - 25.81)/26.453 = 2.43
a tract is an area of indefinite extent, typically a large one
Quadrangle: 24x24 miles.
Township: 6x6 miles.
Section: 1x1 mile
, Term 6 of 72
Convert 34 inches = ________ links.
34*7.92= 269.28
or (346612)/100 = 269.28
formula = divide the area value by 43560
78124/43560 = 1.8 ac
5.476*66= 361.42 feet
k = 0.7854
Term 7 of 72
What is the name of the device used to measure map area?
densiometer
clinometer
planimeter
pantograph
