Math Periodical Test Fourth Grading Part 2

Milliliter is used to measure small amounts of liquids. A liter is a larger unit of measurement, while a milliliter is a smaller unit that is commonly used for measuring small volumes of liquids. A meter is a unit of measurement for length and is not used for measuring liquids. Therefore, milliliter is the correct answer for measuring small amounts of liquids.

The length of an airplane is typically measured in meters. Meters are a commonly used unit of length in the metric system, which is widely used in many countries around the world. Meters provide a more precise and standardized measurement compared to centimeters, which are smaller units of length. Therefore, using meters to measure the length of an airplane is a more appropriate and practical choice.

The correct answer is 800 because there are 100 centimeters in 1 meter. Therefore, to convert 8 meters to centimeters, we multiply 8 by 100 which equals 800.

The shorter side of a figure or an object is referred to as the width. Width typically refers to the measurement of an object or figure from side to side, perpendicular to the length. It is the measurement of the shorter dimension of an object or figure, while length usually refers to the longer dimension. Height, on the other hand, typically refers to the measurement of an object or figure from bottom to top.

The given answer of 50cm square suggests that the area of the figure is 50 square centimeters. However, without any information or description of the figure or the paper provided, it is impossible to determine the accuracy of this answer.

The most appropriate measure of capacity for a vitamin syrup in a bottle would be 30ml. This is because milliliters (ml) are commonly used to measure small volumes of liquid, such as medication or syrups. The other options, 50 L (liters) and 100 m (meters), are not suitable measures of capacity for a small bottle of syrup. Liters are typically used for larger volumes, such as bottles of water or soda, while meters are used to measure length or distance.

The unit of measure to be used in measuring the height of a puppy is centimeter. This is because centimeters are a smaller unit of measure and are more precise for measuring smaller objects like a puppy's height. Meters are a larger unit of measure and would be more appropriate for measuring larger objects or distances.

The kilogram (kg) is used to measure heavy objects. It is the standard unit of mass in the International System of Units (SI). The gram (g) is a smaller unit of mass, typically used for lighter objects. The liter (L) is a unit of volume, not mass, and is used to measure the capacity of liquids. Therefore, the most appropriate unit for measuring heavy objects is the kilogram (kg).

The distance from the top to the bottom of an object is referred to as its height. Height is a vertical measurement that indicates the extent of an object in the upward direction. In contrast, length refers to the measurement of an object from one end to the other in the horizontal direction, and width refers to the measurement from side to side. Therefore, height is the appropriate term to describe the distance from the top to the bottom of the figure of an object.

The perimeter of a square is calculated by adding the lengths of all four sides. Since all sides of a square are equal, if one side measures 30 cm, then all sides will also measure 30 cm. Therefore, the perimeter of the square will be 30 cm + 30 cm + 30 cm + 30 cm = 120 cm.

The more appropriate measure of capacity for a large pail of paint would be 10 L. This is because a pail of paint typically contains a large amount of liquid, and liters are commonly used to measure liquid capacity. Therefore, 10 L would be a more suitable measure compared to 1ml or 40cm, which are much smaller units of measurement.

To convert centimeters to meters, you need to divide the number of centimeters by 100. In this case, when you divide 300 centimeters by 100, you get 3 meters. Therefore, the correct answer is 3.

The correct answer is 30,000 grams because 1 kilogram is equal to 1000 grams. Therefore, to convert 30 kilograms to grams, we need to multiply 30 by 1000, which gives us 30,000 grams.

A liter is used to measure large amounts of liquids. It is a unit of volume in the metric system and is commonly used to measure liquid quantities such as in cooking, medicine, and industry. A liter is equal to 1,000 milliliters, making it a suitable unit for measuring larger volumes. Centimeter, on the other hand, is a unit of length and milliliter is used to measure smaller amounts of liquids.

The length of a house is typically measured in meters, which is a unit of length in the metric system. Meters are commonly used for larger measurements, such as the dimensions of buildings. Centimeters, on the other hand, are smaller units of length and are more suitable for measuring smaller objects. Therefore, when measuring the length of a house, it is more appropriate to use meters rather than centimeters.

The longer side of a figure or object refers to the measurement that is greater in magnitude compared to the other sides or dimensions. In this case, the correct answer is "Length" as it represents the measurement that is longer or greater in length compared to the width and height.

The given answer provides two types of measuring instruments: centimeter ruler and tape measure. These instruments are commonly used to measure the length or distance of objects. Additionally, the answer also includes meterstick and rul, which are likely misspellings or variations of ruler. Overall, the answer accurately identifies different types of measuring instruments.

To convert grams to kilograms, we divide the number of grams by 1000. In this case, Papa bought 4000 grams of meat, so we divide 4000 by 1000 to get 4 kilograms. Therefore, the correct answer is 4kg.

There are 100 centimeters in 1 meter. This is because the metric system is based on powers of 10, and there are 100 centimeters in a meter. This means that if you were to divide a meter into 100 equal parts, each part would be 1 centimeter in length. Therefore, the correct answer is 100cm.

The correct answer is 1000 grams because there are 1000 grams in 1 kilogram. The prefix "kilo-" in the metric system denotes a factor of 1000, so when converting from kilograms to grams, we multiply by 1000. Therefore, 1 kilogram is equal to 1000 grams.
