COSC 275 -Exam 1 And 2 Practice
Questions and Answers.
1 cubic yard= ? cubic feet - Answer 27
1 sq ft.= ? sq in. - Answer 144
1 cubic ft. = ? cubic in. - Answer 1728
board foot formula - Answer T x W x L / 12
-T = the thickness of the board in inches
-W = the width of the
board in inches
-L = the length of the board in feet.
Board foot example:
how many board feet are in a 16 foot long
piece of 2 x 8 lumber? - Answer 2 x 8 x = 21.33 board feet
18'-8"= ?' - Answer 18.667'
Converting to decimal feet - Answer X"/12
Area of a circle - Answer A=πr²
Drilled Hole Volume per foot - Answer -Diam.=CF
-12" 0.785
-14" 1.069
-16" 1.396
-18" 1.767
-20" 2.182
#3 Reinforcing Bar= ? LF - Answer 0.376
#4 Reinforcing Bar= ? LF - Answer 0.668
, #5 Reinforcing Bar= ? LF - Answer 1.043
#6 Reinforcing Bar= ? LF - Answer 1.502
#7 Reinforcing Bar= ? LF - Answer 2.044
#8 Reinforcing Bar= ? LF - Answer 2.670
#9 Reinforcing Bar= ? LF - Answer 3.400
#10 Reinforcing Bar= ? LF - Answer 4.303
#11 Reinforcing Bar= ? LF - Answer 5.313
Roof Slope Conversion - Answer slope=slope conversion
1 & 12 =1.0035
2 & 12=1.0138
3 & 12=1.0308
4 & 12=1.0541
5 & 12=1.0833
General Rule 1 - Answer Work as a team member: takeoff must be clearly labeled with
symbols, captions, sketches or notes to avoid any possible misinterpretation.
General Rule 2 - Answer Be organized
-Organize and label the worksheet so that it is clear as to the project, building component,
description, location(s), quantities, dimensions (such as length, width, and depth or height).
General Rule 3 - Answer Best approach: the normal sequence of construction
-allows repetitive use of common quantities between divisions, i.e. foundation, flooring, ceiling
and roof areas.
General Rule 4 - Answer Read all notes and text on a sheet of drawings first and note the
scales use
