Your Answer: Choice Number 1 (True) is correct. See Page 6, Estimatics Study Guide

For questions number 6 and 7, use the following information: A room is 16’6” long, 12’3” wide, with a ceiling height of 8’. The room has the following doors and windows: Sliding Glass Door – 6’0” x 6’8” Entry Door – 2’6” x 6’8” Window A – 2’0” x 4’0” Window B – 5’0” x 6’0” (7) How many LF of baseboards are in the room?

1. 57.5 LF 2. 51.5 LF 3. 57.8 LF 4. 48.5 LF

Your Answer: Choice Number 2 (51.5 LF) is correct. When calculating LF of the baseboards, you will calculate for the perimeter of the room and deduct any openings for doors greater than the standard door size of 3’0” x 6’8”. In this example, you must only deduct for the sliding glass door as it is bigger than the standard size door. When calculating for the baseboard, you will only need to deduct the width of the door as this is the only measurement that effects baseboards.

1. 168 sf 2. 232.33 sf 3. 192.99 sf 4. 632.28 sf

Your Answer:

The walls are 8’ high. 

The doors are 2’6” x 6’8”. 

14x 8x 2= 224 12x 8x 2= 192 14x 12 = 168

8.33x 8x 2= 133.28 3x 8x 2= 48

8.33x 3 = 24.99 790.27

14x 8= 112 12x 8= 96 3x 8= 24 Total 232

14x 12= 168 3x 8.33= 24.99 Total 192.99

Choice 3 (192.99 sf) is correct. Remember this is carpet PAD. There is no need to calculate waste for carpet pad, only the actual carpet. Therefore, in this example, it is only asking for actual square footage. Also, for the purposes of this example, it says that carpet pad is sold in 6’ wide rolls. This is extraneous information as when calculating for carpet pad, you only need to calculate for square footage of the room in question.

(36) Refer to the sample price list. What is the cost to remove a roof mount power attic vent? 1. $206.25 2. $14.47 3. $220.82

1. 180.08 lf 2. 200 lf 3. 173.16 lf 4. 92 lf

Your Answer:

Choice 3 (173.16 sf) is the correct choice. Calculating for drip edge means that you are calculating for the perimeter. See calculation above.

(43) Refer to the diagram above. How many square feet of carpet will be needed to replace the carpet in the living room only? Do not include the hall in the measurements. There is one seam in the room that runs left to right. The carpet is a 12’ wide roll.

1. 438.92 sf 2. 637.92 sf 3. 631.92 sf 4. 459 sf

Your Answer: Add 3” to the length!! Choice 2 (637.92) is correct. Although the room measurement is 26.33, you must always add 3 inches for the waste which calculates to 26.58. (26’ 4” + 3” = 26.7” or 26.58)

46 (rear) + 46 (front) + 36.58 (left )+ 10.92 (front right) + 4 (front 

left) + 29.66 (right) = 173.16 lf 

Right Measurement was obtained as follows: 

Subtract front left side (4) from front right side (10.92) which 

equals 6.92. 

Subtract 6.92 from left side (36.58) which equals 29.66. 

12x 26.58= 318.96 12x 26.58= 318.96

Total 637.92
