Adding the stairs to your deck can be the most
difficult part of the project. For exterior stairs, a rise between 6" and 8" and a run
between 10" and 13", for each step, is usually acceptable.
If the height from the deck surface to the ground where the stairway
ends is 28" and the length from the edge of the deck to the point where the stairway ends is
45", what will be the rise and run of each step if you build four steps? a. | 5” rise and
10 ½” run | c. | 7” rise and
11 ¼” run | b. | 6” rise and 10 ¾”
run | d. | 8” rise and
12 ½” run | | | | |

Dry
rock walls are constructed without benefit of any cementing substance. The photo shows a top wall; 3
foot high and 20 foot long dry stack wall and a bottom dry stack wall of 2 foot high and 30 foot long
of Tennessee fieldstone.
The secret to
the construction of a sound dry wall is building the face of the wall at such an angle that the soil
behind will support the weight of the wall, while the weight of the rock will keep the soil in its
proper place. The angle of the front of the wall is known as the batter. The
minimum batter of a dry rock wall is 2” of lean for each 1’ in height.
What should be the top wall’s batter?
A 1’ high and 10’ long section of wall requires 1 ton
of Tennessee fieldstone, How much rock was needed to build the top
wall?
a. | 2”
Batter, 6 tons Tennessee Field Stone | b. | 4”
Batter, 4 tons Tennessee Field Stone | c. | 6”
Batter, 6 tons Tennessee Field Stone | d. | 8” Batter, 4 tons Tennessee Field

Measure Pond Dimensions – Measure the maximum
width and length of the pond; then determine the smallest rectangle that would enclose the pond area.
Calculate the liner – To allow for pond depth, decide on the
maximum depth of the pond, double it, and add this figure to the width and length of the rectangle.
Formula: Depth of pond x 2 + maximum
width
Depth of pond x 2 + maximum length
What size
liner would you need for a pond that will fit into a 14’ wide x 16’ long area and will be
dug 30” deep? a. | 18’ x 20’ liner | c. | 20’ x 22’ liner | b. | 19’ x
21’ liner | d. | 21’ x
23’ liner | | | | |

Use
the given formula to estimate the number of cement blocks (8 x 8 x 16) you will need to build a
foundation wall 24 foot long and 2 foot high a foundation wall.
Formulas:
1. Height
of wall x 1 ½ = number of courses
2. Length
of wall x ¾ = number of blocks in each course
3. Number
of courses x blocks per course = number of blocks a. | 24 blocks | c. | 54 blocks | b. | 38
blocks | d. | 62
blocks | | | | |

A
yard of concrete is the amount that will fill one cubic yard of space. Calculate the amount of
concrete to order for a 12’ x 20’ patio poured 4 inch thick.
Formula: Width (in feet) x Length (in feet) x Thickness
(in feet) divided by 27 = number of cubic yards
In this case, the amount of concrete you would need to order would
be: a. | 1
yards | c. | 3
yards | b. | 2 yards | d. | 4 yards | | | | |
