# Free Measurements 01 Practice Test - 5th Grade

Standard unit of capacity is _________.

A.

Metre

B.

Litre

C.

Gram

D.

Kilogram

#### SOLUTION

Solution : B

'Litre' is the standard unit of capacity.

1 kilometre = ______ metres

A.

10

B.

100

C.

1000

D.

10000

#### SOLUTION

Solution : C

The conversion factor for kilometre to metre is 1000.
When we convert a bigger unit (km) to a smaller unit (m), we multiply.

Therefore, 1 km = 1×1000 = 1000 m

Half a metre is ______.

A.

500 m

B.

500 cm

C.

50 m

D.

50 cm

#### SOLUTION

Solution : D

We know that 1 m = 100 cm

Half a metre = 100 cm ÷ 2 = 50 cm

To convert length given in metres (m) into centimetres (cm) we:

A.

divide by 100

B.

multiply  by 100

C.

divide by 1000

D.

multiply by 1000

#### SOLUTION

Solution : B

When we convert a larger unit (m) to a smaller unit (cm), we multiply by the conversion factor.

Therefore, to convert length given in metres (m) to centimetres (cm) we have to multiply by 100.

Which of the following would you use to measure the weight of a rock ?

A.

Measuring tape

B.

Balance scale

C.

Compass

D.

Measuring can

#### SOLUTION

Solution : B

Measuring tape is used to measure the length. For example the length of a cloth. Compass shows the direction. Measuring can is used to measure the volume of a liquid.

The balance scale is an instrument used to measure the mass. It is the device for weighing and find how much the object weighs.

Arrange the following in order of their increasing capacities. A.

Bucket, Jug, Cup, Spoon

B.

Spoon, Jug, Bucket, Cup

C.

Spoon, Cup, Jug, Bucket

D.

Cup, Jug, Spoon, Bucket

#### SOLUTION

Solution : C

If we observe the picture, we see that the spoon is the smallest object which can hold the least quantity of liquid.

The cup has more capacity than the spoon.

The jug has more capacity than both the spoon and the cup.

The bucket can hold more liquid  compared to the spoon, the cup and the jug.

300 g + ___ g = 1 kg

A.

600

B.

700

C.

800

D.

1000

#### SOLUTION

Solution : B

We know that, 1 kg = 1000 g

We already have 300 g,
1000 g - 300 g = 700 g

Therefore, 300 g + 700 g = 1000 g

Find the length of the pencil shown on the scale. A.

5 cm

B.

5.5 cm

C.

6 cm

D.

6.5 cm

#### SOLUTION

Solution : A

If we observe the picture, the pencil on the scale is starting from 1 cm. Ideally, it should start from zero. So, subtract 1 cm from 6 cm.

i.e., Length of the pencil =6cm1cm=5cm A.

100 mL

B.

200 mL

C.

300 mL

D.

400 mL

#### SOLUTION

Solution : D

Capacity of 5 cups=2 litres

When we convert a larger unit (L) to a smaller unit (mL), we multiply the given measure by powers of 10.

Capacity of 5 cups=2×1000 mL   (1 litre=1000 mL)
=2000 mL
Capacity of 1 cup=20005 mL
=400 mL

Thus, the capacity of 1 cup equals 400 mL.

Find the total weight 4 dumbells if one dumbell weighs 800 grams.

A.

4 kg

B.

0.32 kg

C.

32 kg

D.

3.2 kg

#### SOLUTION

Solution : D

Weight of 1 dumbbell =800 gWeight of 4 dumbbells=800 g×4
=3200 g

Since the options are in kilograms, we need to convert 3200 g to kg.

When we convert a smaller unit (g) to a larger unit (kg), we divide the given measure by the conversion factor.

1 kg=1000 g
3200 g=32001000 kg
=3.2 kg

Thus, the weight of 4 dumbbells is 3.2 kg.
