EIAT and NEIEP Test Trade Math and Measurements 1 — Questions and Answers
Question 1: A conduit run requires bends at 22.5°, 45°, and 90°. What is the total degrees of bend?
- 135°
- 157.5° (Correct answer)
- 180°
- 202.5°
Correct answer: 157.5°
Adding the three bends: 22.5° + 45° + 90° = 157.5° total bend in the conduit run.
Question 2: If a wire has a resistance of 0.5 ohms and carries 10 amperes, what is the voltage drop across the wire?
- 0.05V
- 5V (Correct answer)
- 20V
- 50V
Correct answer: 5V
Using Ohm's Law: V = I × R = 10A × 0.5Ω = 5 volts drop across the wire.
Question 3: Convert 3/4 inch to its decimal equivalent.
- 0.50
- 0.65
- 0.75 (Correct answer)
- 0.80
Correct answer: 0.75
3 ÷ 4 = 0.75, so 3/4 inch equals 0.75 inches in decimal form.
Question 4: A room measures 12 feet × 15 feet. What is its area in square feet?
- 27 sq ft
- 54 sq ft
- 144 sq ft
- 180 sq ft (Correct answer)
Correct answer: 180 sq ft
Area = length × width = 12 ft × 15 ft = 180 square feet.
Question 5: What is 15% of 240?
- 24
- 30
- 36 (Correct answer)
- 48
Correct answer: 36
15% of 240 = 0.15 × 240 = 36.
Question 6: A cable tray runs 85 feet. If conduit costs $2.40 per foot installed, what is the total material cost?
- $176
- $196
- $204 (Correct answer)
- $216
Correct answer: $204
85 feet × $2.40/foot = $204.00 total installed cost.
