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.

How many milliliters are in 1.5 liters?
- A. 15 mL
- B. 1,500 mL
- C. 150 mL
- D. 150,000 mL
Correct Answer: B
Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.
How many grams are in 2 kilograms?
- A. 200 grams
- B. 2000 grams
- C. 20 grams
- D. 2 grams
Correct Answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 2 kilograms is equal to 2 x 1000 = 2000 grams. Choice A (200 grams) is incorrect as it represents the value of 0.2 kilograms. Choice C (20 grams) is incorrect as it represents the value of 0.02 kilograms. Choice D (2 grams) is incorrect as it represents the value of 0.002 kilograms.
What is the equivalent of 0.3 milliliters?
- A. 0.03 ml
- B. 0.3 ml
- C. 3 ml
- D. 30 ml
Correct Answer: B
Rationale: 0.3 milliliters is equivalent to 0.3 ml. This is a precise measurement commonly used in medical settings for administering small doses of liquid medication. It is important to understand and recognize the decimal point placement when converting between milliliters and other volume units. Choice A (0.03 ml) is incorrect as it represents a smaller amount than 0.3 ml. Choice C (3 ml) and Choice D (30 ml) are also incorrect as they are larger measurements and do not match the given amount of 0.3 ml.
What is 0.004 as a simplified ratio?
- A. 1:250
- B. 4:35
- C. 7:28
- D. 4:00
Correct Answer: A
Rationale: To convert 0.004 to a ratio, we first express it as 4/1000, which simplifies to 1/250. Hence, 0.004 is equivalent to the simplified ratio of 1:250. Choice B, 4:35, is incorrect as it does not reflect the correct conversion. Choice C, 7:28, is incorrect because it does not represent the simplified ratio of 0.004. Choice D, 4:00, is incorrect as it does not simplify to the original decimal value.
How many liters (L) are equal to 1 kiloliter?
- A. 100 liters
- B. 1,000 liters
- C. 10 liters
- D. 10,000 liters
Correct Answer: B
Rationale: To convert kiloliters to liters, you multiply by 1,000. Therefore, 1 kiloliter 1,000 = 1,000 liters. Choice A (100 liters) is incorrect because it represents only 1/10th of a kiloliter. Choice C (10 liters) is incorrect as it represents only 1/100th of a kiloliter. Choice D (10,000 liters) is incorrect as it is 10 times bigger than a kiloliter.
