Step: 3

So, the best estimate of the capacity of a water can is 2 liters.

Correct Answer is : 2 liters

Step: 1

The weight of the camera can be lighter than 1 kilogram.

Step: 2

So, the best estimate for the weight of the camera is lighter than 1 kilogram.

Correct Answer is : lighter than 1 kilogram

Step: 1

The bottle can hold about 1 liter.

Step: 2

So, the estimate for the capacity of the bottle shown is about 1 liter.

Correct Answer is : about 1 liter

Step: 1

The objects in Figure 2 and Figure 3 cannot hold 1 litre.

Step: 2

The object in Figure 1 can hold less than 1 litre.

Step: 3

So, among the given objects, the object in Figure 1 can hold about 1 litre.

Correct Answer is : Figure 1

Step: 1

A cup and a tablespoon cannot hold 50 litres of water. They are too small to hold 50 litres of water.

Step: 2

A water jug can hold a maximum of 5 litres of water.

Step: 3

Usually people store plenty of water in tanks. So, a tank can hold 50 litres of water.

Correct Answer is : a tank

Step: 1

100 kilograms and 10 kilograms are too big to measure the weight of a papaya.

Step: 2

10 grams is too small to measure the weight of a papaya.

Step: 3

A papaya can weigh about 2 kilograms.

Step: 4

So, the estimated weight of a papaya is 2 kilograms.

Correct Answer is : 2 kilograms

Step: 1

The given object is a syringe.

Step: 2
