  • 2. 

    The prefix milli means

    • Base unit ÷ 1000

    • Base unit

    • 1000 x base unit

    Correct Answer
    A. Base unit ÷ 1000
    Explanation
    The prefix "milli" is used to denote one thousandth of a base unit. Therefore, when the base unit is divided by 1000, it represents the value of the prefix "milli".

    Rate this question:

  • 3. 

    The prefix centi means

    • Base unit ÷ 100

    • Base unit x 1000

    • 100 x base unit

    Correct Answer
    A. Base unit ÷ 100
    Explanation
    The prefix "centi" refers to a division by 100. It indicates that the unit being referred to is one hundredth of the base unit. For example, if the base unit is meter, then "centimeter" would be one hundredth of a meter. Therefore, the correct answer is "base unit ÷ 100".

    Rate this question:

  • 4. 

    The prefix kilo means

    • Base unit ÷ 1000

    • Base unit

    • 1000 x base unit

    Correct Answer
    A. 1000 x base unit
    Explanation
    The prefix "kilo" is used to denote a multiplication factor of 1000. Therefore, when the base unit is multiplied by 1000, it represents the meaning of the prefix "kilo".

    Rate this question:

  • 5. 

    One hectare is equivalent to a square of sides 100 m in length

    • True

    • False

    Correct Answer
    A. True
    Explanation
    One hectare is a unit of measurement for land area and is equal to 10,000 square meters. Since a square with sides of 100 meters has an area of 10,000 square meters, it is equivalent to one hectare. Therefore, the statement "one hectare is equivalent to a square of sides 100 m in length" is true.

    Rate this question:

  • 6. 

    1 cm³ = 1 mL = 1 gm (water)

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because 1 cm³ is equal to 1 mL, and 1 mL of water weighs 1 gram. This is because water has a density of 1 gram per milliliter. Therefore, 1 cm³ is equal to 1 gram of water.

    Rate this question:

  • 7. 

    34 metres is the same as

    • 340 cm

    • 3400 mm

    • 3400 cm

    • 34000 cm

    Correct Answer
    A. 3400 cm
    Explanation
    To convert metres to centimetres, we multiply the number of metres by 100. In this case, 34 metres multiplied by 100 equals 3400 centimetres. Therefore, 34 metres is the same as 3400 cm.

    Rate this question:

  • 8. 

    34 metres is the same as

    • 340 cm

    • 3400 mm

    • 34000 cm

    • 34000 mm

    Correct Answer
    A. 34000 mm
    Explanation
    To convert metres to millimetres, we multiply by 1000. Therefore, 34 metres is equal to 34,000 millimetres.

    Rate this question:

  • 9. 

    1 L of water has a mass of

    • 10 kg

    • 1 kg

    • 100 g

    • 100 kg

    Correct Answer
    A. 1 kg
    Explanation
    The density of water is 1 g/mL or 1 kg/L. Therefore, 1 L of water has a mass of 1 kg.

    Rate this question:

  • 10. 

    The prefix Mega means

    • Base unit ÷ 1000, 000

    • Base unit x 1000, 000

    • 100, 000 x base unit

    Correct Answer
    A. Base unit x 1000, 000
    Explanation
    The prefix "Mega" is used to denote a factor of one million. Therefore, when applied to a base unit, it multiplies the base unit by 1,000,000.

    What is the base unit for capacity?

    • Litre

    • Cubic centimetre

    • Pint

    Correct Answer
    A. Litre
    Explanation

  • 13. 

    1 cm³ has a capacity of

    • 10 mL

    • 100 mL

    • 1 mL

    Correct Answer
    A. 1 mL
    Explanation
    The capacity of 1 cm³ is 1 mL. This is because 1 cm³ is equal to 1 milliliter. The conversion factor between cubic centimeters and milliliters is 1:1, meaning that they have the same volume. Therefore, 1 cm³ has a capacity of 1 mL.

  • 17. 

    A rectangle measuring 10 m x 25 m has an area of

    • 2, 500, 00 cm²

    • 25, 000 cm²

    • 250 cm²

    • 2500 m²

    Correct Answer
    A. 2, 500, 00 cm²
    Explanation
    The given rectangle has dimensions of 10 m x 25 m. To find the area, we multiply the length and width of the rectangle. Converting the dimensions to centimeters, we get 1000 cm x 2500 cm. Multiplying these values gives us an area of 2,500,000 cm², which matches the given answer of 2,500,00 cm².

    What is the unique base unit for area?

    • M²

    • Acre

    • Hectare

    Correct Answer
    A. Hectare
    Explanation
    The hectare is the unique base unit for area. It is a metric unit commonly used in measuring land area. The hectare is equal to 10,000 square meters and is widely used in agriculture and land management. It provides a convenient unit for measuring large areas of land. The other options, m² and acre, are also units of area, but they are not considered base units. The m² is a derived unit from the SI system, and the acre is primarily used in the United States and the UK.
