Test: Weigh It, Pour It - Class 4 MCQ

The only option that can be measured in litres is the quantity of water in a bottle.
Here's why:

• Length is measured in units like metres or centimetres.
• Weight is measured in units like kilograms or grams.
• Temperature is measured in degrees Celsius or Fahrenheit.

Thus, litres are used to measure volume, such as the amount of liquid in a container.

To determine the number of 100 ml bottles needed to fill a 1 litre container, follow these steps:

• 1 litre is equal to 1000 ml.
• Divide 1000 ml by 100 ml per bottle.
• This results in 10 bottles required.

To find out how many boxes are needed to make up 1 kilogram, follow these steps:

• A box weighs 500 grams.
• 1 kilogram is equal to 1000 grams.
• Divide 1000 grams by 500 grams per box: 1000 / 500 = 2.
• Therefore, 2 boxes are required.

To find out how much water is wasted in a day if a tap drips at a rate of 500 ml per hour:

• 1 hour = 500 ml
• 1 day = 24 hours
• Water wasted in a day = 500 ml/hour × 24 hours

Therefore, water wasted in a day = 12,000 ml.

Since 1 litre is 1,000 ml, 12,000 ml is equal to 12 litres.

The unit of capacity among the given options is millilitre.

• Millilitre is a metric unit used to measure volume or capacity.
• Commonly used in measuring liquids.

To convert kilograms to grams:

• 1 kilogram equals 1000 grams.

This is because the metric system defines a kilogram as 1000 times the mass of a gram.

To determine how many 50 ml bottles are needed to fill a 1 litre container, follow these steps:

• 1 litre is equivalent to 1000 ml.
• Divide 1000 ml by 50 ml per bottle.
• The calculation is: 1000 ml ÷ 50 ml = 20 bottles.

Therefore, 20 bottles are required to fill a 1 litre container.

The solution to find the total weight is simple:

• Each packet weighs 1 kg.
• There are 10 packets.
• Multiply the number of packets by the weight of each packet: 10 kg.

Therefore, the total weight is 10 kg.

The measurement used for smaller quantities of liquid is millilitres.

Litres are used for larger quantities of liquid.
Measurements like kilograms and grams are for weight, not liquid volume.

A litre is equivalent to 1000 millilitres.

• This is because 1 litre is defined as 1000 millilitres.
• The metric system uses this conversion: 1 litre = 1000 ml.
