How many cubic yards of concrete is required for the footing shown, if it is 75 feet
long? - ANSWER-2 ½ cubic yards

Explanation:
Step 1: Figure out the area of the face of the footing. Top area = 6" x 9" = 54
square inches Bottom area = 6" x 12" = 72 square inches Total area = 54 + 72 =
126 square inches Step 2: Convert square inches into square feet.126 ÷ 144 = 0.875
square feet Step 3: Get volume by multiplying the previous answer by the
length.0.875 x 75 = 65.625 cubic feet Step 4: Convert cubic feet into cubic
yards.65.625 ÷ 27 = 2.43 cubic yards Since there is no exact answer, round up the
number.

What is the volume of a cylinder if the diameter equals 3 feet and the length equals
to 12 feet? - ANSWER-84.78 cubic feet

Explanation:
There are two ways to solve the problem. However, regardless of which method is
used, you need to first determine the area of the circle then multiply it by the
length. Traditional Method Use the following formula: Area of the circle = π x r x
where π = 3.14 and radius (r) = 1.5 feet (half of the diameter length) Area = 3.14 x

,1.5 x 1.5Area = 7.065 sq. ft. Multiply area by the length to find the volume.7.065 x
12 = 84.78Shortcut Method Area of the circle is 78.5% of the square. Treat the
circle as a square and solve for the area. Find the area of the square instead of the
circle.3' x 3' = 9 sq. ft. Since circle is 78.5% of the square, multiply area of the
square by 78.5% (or .785 if there is no percentage sign on the calculator).9 sq. ft. x
.785 = 7.065 square feet Multiply area by the length to find the volume.7.065 x 12
= 84.78 cubic feet

Where are spiral rebar ties used? - ANSWER-In round columns

Control joints in sidewalks should be spaced at what intervals? - ANSWER-Equal
to the width of the slab

Explanation:
Generally, the control joints in sidewalks should be spaced equal to the width of
the slab, but not more than 6 feet apart.

One cubic foot of cement weighs approximately: - ANSWER-95 lbs.

How many cubic yards of concrete is required for a 4" slab with the diameter of 15
feet? - ANSWER-2 ½ cubic yards

Explanation:
Traditional Method Use the following formula: Area of the circle = π x r x where π
= 3.14 and radius (r) = 7.5 feet (half of the diameter length)Area = 3.14 x 7.5 x
7.5Area = 176.625 sq. ft. Multiply area by the depth of the slab (in feet) to find the
volume in cubic feet.176.625 x .333 = 58.82 cubic feet Convert cubic feet into
cubic yards.58.82 ÷ 27 = 2.18 cubic yards Since 2.18 is not a given option, round
up the number to 2.5 cubic yards Shortcut Method This problem can be solved
using a much simpler method. First is to find the area of the square, then convert it

, into the area of the circle by multiplying it by 78.5%.Area of the square = 15' x 15'
= 225 square feet Area of the circle = 225 x .785 = 176.625 square feet Divide the
volume by 81 to solve for the cubic yards for a 4" slab.176.625 ÷ 81 = 2.18 cubic
yards Since 2.18 is not a given option, round up the number to 2.5 cubic yards

The normal tolerance for the location of bends and ends of reinforcing bar is: -
ANSWER-+/- 2 inches

How many cubic yards of backfill are required for a 3' x 5' trench, 1500 ft long,
with a 1-foot diameter pipe? - ANSWER-789.72

Explanation:
Step 1. Find the net face area of the trench deducting for pipe. Face area including
pipe: 3 x 5 = 15 square feet Area of the pipe: 𝐴=𝜋𝑟2A = 3.14 x .5 x .5A =
0.785Find the face area of the trench minus area of the pipe, which will give you
the net area for the backfill.15 - 0.785 = 14.215Step 2. Find the total volume of the
backfill.14.215 x 1500 = 21322.5 cubic feet Convert the volume into cubic
yards.21322.5 ÷ 27 = 789.72 cubic yards

When can the live load be calculated by multiplying the height, width and length of
a pour and dividing by the deadload? - ANSWER-Never

Tensile strength in concrete is achieved by: - ANSWER-The use of steel
reinforcement.

Refer to the house plan. What is the total cost for the foundation slab if the
contractor charges $3.54 per square foot? - ANSWER-$6524.90
