Test: Measurement - Grade 4 MCQ

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.

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.

The conservation of volume means that the quantity of a substance remains constant even if the shape of the container changes. This principle is observed when pouring liquids from one container to another.

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.

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.

A weighing balance works by comparing the weights of two objects. When both pans are equal, it indicates that the weights are balanced, which is fundamental in measuring mass accurately.

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.

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.

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.

If two objects are balanced on a weighing scale, it indicates that they have the same mass. This balance is essential for accurate weight measurements and comparisons.

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

You can measure the capacity of a large container by counting how many cups it takes to fill it. This practical approach is useful in cooking and other scenarios where precise measures are less critical.

The perimeter of a rectangle is calculated by the formula: 2 × (length + width). For a garden measuring 4 m by 3 m, the perimeter is 2 × (4 + 3) = 2 × 7 = 14 m. Thus, 14 m of fencing is needed.

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.

To add lengths measured in metres and centimetres, you align the metres and centimetres, add them separately, and carry over if necessary. This ensures accuracy in the final measurement.

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.

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.

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.

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

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.
