1. What is the formula for calculating the volume of a solid object?

• A. V = W/L
• B. V = L x W x H
• C. V = W/H
• D. V = L/W

Correct answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H, where L represents the length, W represents the width, and H represents the height. Choice A (V = W/L) is incorrect as it represents a division operation, not multiplication. Choice C (V = W/H) is incorrect as it does not account for the width and height. Choice D (V = L/W) is incorrect as it represents the inverse operation of what is needed to calculate volume.

2. Convert 35.40 kilograms to grams (g).

• A. 354 g
• B. 35,400 g
• C. 3,540 g
• D. 3.54 g

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

3. What does 'm' stand for in the metric system?

• A. meter
• B. mole
• C. milli
• D. micro

Correct answer: A

Rationale: The correct answer is 'meter.' In the metric system, 'm' stands for meter, which is the base unit for length. Choice B, 'mole,' is a unit used in chemistry to represent an amount of substance. Choice C, 'milli,' represents a prefix indicating one-thousandth, and choice D, 'micro,' represents a prefix indicating one-millionth. Therefore, the correct choice is 'A: meter.'

4. How many milligrams are in 1 gram?

• A. 1 mg
• B. 10 mg
• C. 100 mg
• D. 1,000 mg

Correct answer: D

Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.

5. How many liters are in 2,000 milliliters?

• A. 0.2 liters
• B. 2 liters
• C. 0.02 liters
• D. 20 liters

Correct answer: B

Rationale: The correct answer is B: 2 liters. To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 2,000 milliliters is equal to 2 liters (2000 ÷ 1000 = 2). Choices A, C, and D are incorrect because they incorrectly convert milliliters to liters, resulting in values that are too low (A and C) or too high (D).
