All questions of Measurement for Class 3 Exam

When measuring capacity, what is a common non-standard unit?
  • a)
    Grams
  • b)
    Cups
  • c)
    Metres
  • d)
    Litres

Flembe Academy answered
Cups are used as non-standard units for measuring capacity. They vary in size but help in estimating how much a container can hold, especially in cooking and everyday usage.

If you have 3 metres and 25 centimetres, how many centimetres is that in total?
  • a)
    350 cm
  • b)
    300 cm
  • c)
    325 cm
  • d)
    275 cm
Correct answer is option 'C'. Can you explain this answer?

To convert 3 m and 25 cm to centimetres, multiply the metres by 100 and add the centimetres: (3 × 100) + 25 = 300 + 25 = 325 cm. This method is useful for combining measurements in a single unit.

What is the total weight when adding 313 kg 150 g and 225 kg 375 g?
  • a)
    538 kg 700 g
  • b)
    538 kg 375 g
  • c)
    538 kg 525 g
  • d)
    538 kg 150 g
Correct answer is option 'C'. Can you explain this answer?

To find the total weight, align and add the kilograms and grams separately: (313 kg + 225 kg) and (150 g + 375 g), which results in 538 kg 525 g. This method ensures clarity in weight calculations.

How do you convert 700 cm to metres?
  • a)
    70 m
  • b)
    0.7 m
  • c)
    7 m
  • d)
    0.07 m
Correct answer is option 'C'. Can you explain this answer?

Flembe Academy answered
To convert 700 cm to metres, divide by 100 (since 100 cm = 1 m): 700 cm ÷ 100 = 7 m. This conversion is essential for understanding larger measurements in a more manageable unit.

If you have 2 m 45 cm of ribbon and you cut off 1 m 10 cm, how much ribbon do you have left?
  • a)
    1 m 25 cm
  • b)
    1 m 55 cm
  • c)
    2 m 25 cm
  • d)
    1 m 35 cm
Correct answer is option 'D'. Can you explain this answer?

To find the remaining length of ribbon, convert both measurements to centimetres: (2 m 45 cm = 245 cm) and (1 m 10 cm = 110 cm). Then subtract: 245 cm - 110 cm = 135 cm, which converts back to 1 m 35 cm. This showcases the importance of unit conversion in real-life applications.

Which of the following is a non-standard unit for measuring weight?
  • a)
    Milligrams
  • b)
    Grams
  • c)
    Kilograms
  • d)
    Stones
Correct answer is option 'D'. Can you explain this answer?

Flembe Academy answered
Stones are considered a non-standard unit for measuring weight because their size and weight can vary significantly, making them less reliable than standard units like grams and kilograms.

How many millilitres are in 1 litre?
  • a)
    500 ml
  • b)
    100 ml
  • c)
    1000 ml
  • d)
    10 ml
Correct answer is option 'C'. Can you explain this answer?

Flembe Academy answered
There are 1000 millilitres in 1 litre (1 L = 1000 mL). This conversion is fundamental in measuring liquid capacities accurately.

How many centimetres are there in one metre?
  • a)
    50 cm
  • b)
    100 cm
  • c)
    75 cm
  • d)
    200 cm
Correct answer is option 'B'. Can you explain this answer?

Flembe Academy answered
There are 100 centimetres in one metre (1 m = 100 cm). This relationship is crucial for converting between these two units when measuring length.

What is the result of subtracting 15 kg 65 g from 36 kg 125 g?
  • a)
    21 kg 60 g
  • b)
    19 kg 60 g
  • c)
    20 kg 100 g
  • d)
    21 kg 65 g
Correct answer is option 'A'. Can you explain this answer?

To subtract 15 kg 65 g from 36 kg 125 g, align the kilograms and grams: (36 kg - 15 kg) and (125 g - 65 g), which results in 21 kg 60 g. This method is essential for precise weight calculations.

If a jug holds 2 bottles of water, how many glasses can it fill if 6 glasses equal the same amount?
  • a)
    1 glass
  • b)
    6 glasses
  • c)
    4 glasses
  • d)
    2 glasses
Correct answer is option 'B'. Can you explain this answer?

If 6 glasses can fill the same jug that holds 2 bottles, it means that the capacity of the jug is equivalent to 6 glasses of water. This understanding of capacity relationships helps in practical situations like cooking or serving drinks.

Which unit would you use to measure the length of a pencil box?
  • a)
    Centimetres
  • b)
    Metres
  • c)
    Kilograms
  • d)
    Litres
Correct answer is option 'A'. Can you explain this answer?

Flembe Academy answered
Centimetres are most appropriate for measuring shorter lengths, such as the length of a pencil box. Using the right unit enhances accuracy in everyday measurements.

What is the result of adding 25 m 32 cm and 16 m 8 cm?
  • a)
    40 m 40 cm
  • b)
    41 m 25 cm
  • c)
    41 m 32 cm
  • d)
    41 m 40 cm
Correct answer is option 'D'. Can you explain this answer?

Flembe Academy answered
To add 25 m 32 cm and 16 m 8 cm, align the metres and centimetres: (25 m + 16 m) and (32 cm + 8 cm), resulting in 41 m 40 cm. This process of aligning helps avoid errors in addition.

What is 7621 cm in terms of metres and centimetres?
  • a)
    76 m 212 cm
  • b)
    76 m 21 cm
  • c)
    7 m 621 cm
  • d)
    762 m 21 cm
Correct answer is option 'B'. Can you explain this answer?

To convert 7621 cm to metres and centimetres, the last two digits (21) represent centimetres, and the remaining (76) represent metres, giving 76 m 21 cm. This method helps in better understanding large measurements.

What is the standard unit of measurement for length?
  • a)
    Metres
  • b)
    Kilograms
  • c)
    Grams
  • d)
    Litres
Correct answer is option 'A'. Can you explain this answer?

The standard unit for measuring length is the metre (m). It provides an accurate way to measure longer distances, while smaller lengths are measured in centimetres (cm). This standardization allows for consistent measurements across different contexts.
