Multiple Choice

Identify the letter of the choice that best completes the statement or answers the question.

Your new deck requires 16 footings poured 16” deep. After the building inspector approves the footing holes, you are ready to pour concrete. To determine the number of 60 pound bags needed to fill a 12" diameter hole, divide the depth of the hole in inches by 9. What is the total number of 60 pound bags of concrete needed to pour your footings?

D= depth of hole in inch

N= number of bags per hole

H= total number of holes

T= total number of bags

N= D/9

T = N x H

Select from the below answers:

a.	2	c.	17
b.	9	d.	29

Unmanageable slopes pose a danger to those who must mow or rake them. They may also be affected by erosion from run off that can create unattractive ruts that just grow deeper and wider over time. With a little effort, you can take control of that slope and convert it into a decoratively landscaped area that looks great and is easier to maintain.

Modern retaining wall systems can be delivered to your home on pallets. The best part of the job is that the blocks interlock and require no mortar. Retaining wall blocks in morterless systems have a lip on the bottom rear side to lock the blocks together and create a step effect, with the wall leaning backwards. When the cavity behind the wall is filled with soil, the blocks are pushed forward, strengthening the joint between the lips and the underlying blocks. The blocks are tapered from the front face to the rear to allow easy formation of curves. Each block measures 6” thick x 12” long x 6” deep.

You need to construct a wall that is 2’ high and 20’ long. One pallet equals 100 blocks. How many pallets will you need to order?

Select from the below answers:

a.	1 pallet	c.	3 pallets
b.	2 pallets	d.	4 pallets

Standard bricks measure 4 x 8 inches, so you'll need about 45 bricks to cover every 10 square feet of walkway. For rectangular walkways, calculate the square footage by multiplying the length by the width and add about 5 percent to that number for breakage and later repairs. You are preparing to install a brick walkway that is 4 feet wide and 80 feet long. How many bricks will you need?

a.	1305 bricks	c.	1674 bricks
b.	1512 bricks	d.	1829 bricks

Flexible pond liners come in a variety of standard sizes. Some garden suppliers carry large rolls of liner material in standard widths. To estimate the amount of liner you need, determine the actual size of your garden pond. The liner must fit the pond and overlap the edges for proper fit. 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. To provide a 12-inch overlap, add an additional 24 inches to the width and length of the liner. If you want your pond to be 24 inches deep and fit inside a 10ft. x 12ft. rectangle, what size liner should you buy?

Formula:

Formula for Width = Width of pool + (Depth x 2) + 24inches (for overlap)

Formula for Length = Length of pool + (Depth x 2) + 24 inches (for overlap)

a.	10 x 12 foot liner	c.	14 x 16 foot liner
b.	12 x 14 foot liner	d.	16 x 18 foot liner
