3,000 square feet is the total square footage. Ventilation is 1/300 of total
roof square footage, which means that for every 300 square feet of roof area
you need 1 foot of ventilation.
3, = 10 square feet of total ventilation required.
,The ventilation will be split equally between ridge vents and soffit vents.
= 5 square feet of soffit vent required.
(5 square feet of ridge vent would also be required.) - -The required
ventilation for a 3,000 square foot roof is 1/300 of the horizontal roof
projection area. The ventilation will be evenly split between ridge vents and
soffit vents. How many square feet of soffit vent are required to comply with
the ventilation requirements?
a.) 3
b.) 5
c.) 8
d.) 20
-b.) Between $225 and $250.
Step 1: Determine the cost of the 1/2" plywood. There is 32 square feet of
plywood per sheet.
= $108 + $140 = $248 - -You are in the process of determining the cost for
your job. An area measuring 14' x 16' will need 3/4 inch plywood floor
decking. An area measuring 18' x 16' will need 1/2 inch plywood floor
decking. The costs are $20 per sheet for 3/4" plywood and $12 per sheet for
1/2 inch plywood. Calculate the total cost for all of the plywood floor
decking?
a.) Less than $200.
b.) Between $225 and $250.
c.) Between $251 and $299.
d.) More than $300.
-b.) 3.20 feet lower.
To determine the difference in elevation subtract the finish grade from the
benchmark.
, = 118.42 - 115.22 = 3.20 feet lower - -A benchmark on a site plan has an
elevation of 118.42 feet. Finish grade has an elevation of 115.22 feet. The
finish grade is how many feet lower or higher than the benchmark?
a.) 3.20 feet higher.
b.) 3.20 feet lower.
c.) 5.20 feet higher.
d.) 2.20 feet lower.
-c.) 35
First draw a picture of a rectangle. On the outside of the rectangle, label the
long sides at 50 feet and the short sides at 20 feet. On the inside of the
rectangle, label the long sides at 48 feet and the short sides at 18 feet.The
two foot difference on the inside of the rectangle is due to the thickness of
the walls on both sides (12 inches on each side).
Outside area:
Now determine the total outside area that will need to be formed.
= 20+50+20+50 = 140 feet
Each sheet of plywood will cover 8 feet since the foundation is only 4 feet
high.
= feet = 17.5 sheets, which rounds up to 18 sheets of plywood for the
outside forms.
Inside area:
Determine the total inside area that will need to be formed.
= 18+48+18+48 = 132 feet
Each sheet of plywood will cover 8 feet since the foundation is only 4 feet
high.
= feet = 16.5 sheets, which rounds up to 17 sheets of plywood for the
outside forms.
=18 + 1 - -The outside measurements of a 12-inch thick concrete
foundation wall are 20 feet x 50 feet. The distance from the top of the
foundation wall to the top of the footing is 4 feet. Both sides of the
foundation wall will be formed using 4-foot by 8-foot plywood sheets.
How many sheets of plywood will be needed to form the foundation wall?
a.) 17
b.) 29
c.) 35
d.) 42
-b.) 5 feet.
