1. how long are studs in a 8’ tall wall?

a. 92 5/8\ c. 96\
b. 92\ d. 93\

Explanation:

Step1: Convert units

We know that 1 foot = 12 inches. So for question 9, the answer is c. 12.

Step2: Analyze fractions

Since 1 inch is divided into 16 equal parts (16ths), for question 10, the answer is b. 16.

Step3: Consider shop increments

In a shop, the smallest common increment is often 1/16, so for question 11, the answer is a. 1/16.

Step4: Convert feet to inches

Since 1 foot = 12 inches, 4 feet = 4×12 = 48 inches. So for question 12, the answer is d. 48.

Step5: Add mixed numbers

1 1/2 = 1 + 1/2 = 1 + 4/8, 1 1/8 = 1 + 1/8. Then 1 1/2 + 1 1/8=(1 + 1)+(4/8 + 1/8)=2 + 5/8 = 2 5/8. So for question 13, the answer is c. 2 5/8.

Step6: Subtract mixed numbers

3 3/4 = 3 + 3/4 = 3 + 6/8, 1 1/2 = 1 + 1/2 = 1 + 4/8. Then 3 3/4 - 1 1/2=(3 - 1)+(6/8 - 4/8)=2 + 2/8 = 2 1/4. So for question 14, the answer is b. 2 1/4.

Step7: Know nominal size

The nominal size of a 2x4 is 1 1/2" x 3 1/2" (after drying and planing). So for question 15, the answer is b. 1 1/2" x 3 1/2".

Step8: Calculate stud length

An 8' (96") tall wall, but considering the top and bottom plates (usually 3 1/2" in total). 96 - 3 1/2 = 92 1/2. But if we consider some construction standards, 92 5/8" is a common stud length for an 8' wall. So for question 16, the answer is a. 92 5/8".

Answer:

1. c. 12
2. b. 16
3. a. 1/16
4. d. 48
5. c. 2 5/8
6. b. 2 1/4
7. b. 1 1/2" x 3 1/2"
8. a. 92 5/8"
