Units of Measurement

What is the BASE unit of measurement in the metric system for LENGTH?

• Gram

• Liter

• Meter

• Feet

Answer explanation

The base unit of measurement for length in the metric system is the meter. Other options like gram and liter measure mass and volume, respectively, while feet is a unit in the imperial system.

What is the BASE unit of measurement in the metric system for MASS?

• Gram

• Liter

• Meter

• Pound

Answer explanation

The base unit of measurement for mass in the metric system is the gram. Other options like liter and meter measure volume and length, respectively, while pound is a unit in the imperial system.

What is the BASE unit of measurement in the metric system for VOLUME?

• Gram

• Liter

• Meter

• Gallon

Answer explanation

The BASE unit of measurement for VOLUME in the metric system is the Liter. Unlike Gram (mass) and Meter (length), the Liter specifically measures volume, making it the correct choice.

The AREA of an object is reported as ______.

• Grams2

• Liter2

• Meter2

• Gallon2

Answer explanation

The area of an object is measured in square units. The correct unit for area is square meters, denoted as Meter2. Other options like Grams2 and Liter2 are not applicable for area measurement.

The VOLUME of an object is reported as ______.

• Grams3

• Km2

• Meter3

• inches

Answer explanation

The volume of an object is measured in cubic units, which is represented as Meter3 (m³). This indicates the amount of space the object occupies. Other options like grams and km² are not appropriate for volume.

The formula for speed or velocity is _________.

• Mass / Volume

• Time x Distance

• Distance / Time

• Area / Length

Answer explanation

The correct formula for speed or velocity is Distance / Time. This means speed is calculated by dividing the distance traveled by the time taken to travel that distance.

The VOLUME of a liquid is measured in __________.

• miles

• seconds

• ml

• kg

Answer explanation

The volume of a liquid is commonly measured in milliliters (ml), which is a unit of volume. Other options like miles and seconds are not relevant to volume measurement, and kilograms (kg) measure mass, not volume.

Density is the compactness of an object. It's formula is Mass / Volume. What units are used to report the DENSITY of an object?

• grams / cm3

• grams / cm

• grams / cm2

• km / cm3

Answer explanation

Density is calculated as mass divided by volume. The correct unit for density is grams per cubic centimeter (grams/cm³), which indicates mass per unit volume. Other options do not correctly represent this relationship.

What unit is NOT a measurement for TEMPERATURE?

• Kelvin

• Celsius

• Fahrenheit

• Geosphere

Answer explanation

The correct answer is 'Geosphere' because it refers to the solid part of the Earth, not a unit of temperature. Kelvin, Celsius, and Fahrenheit are all standard units used to measure temperature.

What type of measurement is 3D and reported as "CUBED"?

• Temperature

• Volume

• Area

• Mass

Answer explanation

The measurement reported as 'CUBED' refers to volume, which quantifies the three-dimensional space an object occupies. Temperature, area, and mass do not use cubic units.
