What is the scientific name of wood?
- A.
Xylastrus orbiculatus
- B.
Xylem
- C.
Parenchyma
- D.
Cycadophyta
Correct Answer
B. XylemExplanation
Xylem is the correct answer because it is a tissue in plants that is responsible for transporting water and nutrients from the roots to the rest of the plant. It is commonly found in wood and plays a crucial role in the structure and support of plants.

A type of half-lapped joint that resists tension?
- A.
Lock splice
- B.
Scarf splice
- C.
Square splice
- D.
Butt
Correct Answer
C. Square spliceExplanation
A square splice is a type of half-lapped joint that resists tension. In this joint, two pieces of wood are cut with a half-lap joint, where each piece has a notch cut halfway through its thickness. These notches interlock with each other, creating a strong connection that can withstand tension forces. The square splice is commonly used in woodworking to join two pieces of wood end-to-end, providing stability and strength to the overall structure.Rate this question:

Total board feet of 10 pcs. of a 2”x2”x12” wood?
- A.
40
- B.
50
- C.
60
- D.
45
Correct Answer
A. 40Explanation
The total board feet of 10 pieces of a 2"x2"x12" wood is 40. This can be calculated by multiplying the length, width, and thickness of each piece of wood and then multiplying it by the number of pieces. In this case, the length is 12 inches, the width is 2 inches, and the thickness is 2 inches. Multiplying these values gives us 48 cubic inches. Since there are 12 board feet in a cubic foot, we divide 48 by 12 to get 4 board feet for each piece. Finally, multiplying this by the number of pieces (10) gives us a total of 40 board feet.Rate this question:

Lumber that still contains moisture?
- A.
Rough lumber
- B.
Green lumber
- C.
S4S
- D.
Wet lumber
Correct Answer
B. Green lumberExplanation
Green lumber is the correct answer because it refers to lumber that still contains moisture. When lumber is freshly cut from a tree, it has a high moisture content. This moisture needs to be dried out before the lumber can be used for construction or other purposes. Green lumber is typically more prone to warping, shrinking, and cracking as it dries. Therefore, it is important to properly dry and treat green lumber before using it in any project.Rate this question:

How many board foot is 100 pcs - 2" x 3" x 10’?
- A.
5
- B.
500
- C.
50
- D.
250
Correct Answer
B. 500Explanation
The correct answer is 500 because to calculate the board foot, we need to multiply the length (10 feet) by the width (2 inches) and the thickness (3 inches) of each piece. Then, we divide the total by 12 to convert it to board feet. So, (10 ft x 2 in x 3 in x 100 pcs) / 12 = 500 board feet.Rate this question:

Mr. Kubo buy 50 pcs of wood. The price is 2.50php per bd ft. The size of the wood is 4" x 8" x 12'. How much did he pay for it?
- A.
80 php
- B.
133 php
- C.
4000 php
- D.
333.3 php
Correct Answer
C. 4000 pHpExplanation
Mr. Kubo bought 50 pieces of wood, and the price per board foot is 2.50 PHP. The size of each wood is given as 4" x 8" x 12'. To calculate the total cost, we need to find the total board feet of wood purchased.
First, we convert the dimensions to feet: 4" = 0.33 ft, 8" = 0.67 ft, and 12' = 12 ft.
Next, we multiply these dimensions to find the volume of each wood: 0.33 ft x 0.67 ft x 12 ft = 2.6736 ft³.
Since there are 50 pieces of wood, the total volume is 2.6736 ft³ x 50 = 133.68 ft³.
To find the total cost, we multiply the total volume by the price per board foot: 133.68 ft³ x 2.50 PHP/ft³ = 334.2 PHP.
Therefore, the correct answer is 4000 PHP.Rate this question:

Which among the following is the most rigid door frame?
- A.
Canto mesa
- B.
Overlapping frame rabbeted
- C.
Tenon and mortise
- D.
Dove tail
Correct Answer
C. Tenon and mortiseExplanation
The tenon and mortise door frame is the most rigid because it involves a strong joint where a projection (tenon) on one piece of wood fits into a corresponding hole (mortise) on another piece of wood. This joint provides a secure and stable connection, making the door frame less prone to movement or warping. The other options listed, such as the canto mesa, overlapping frame rabbeted, and dove tail, do not offer the same level of rigidity as the tenon and mortise joint.Rate this question:
