What is it?

When something is 'full', it means it has reached its maximum capacity or limit. There is no more space or room left inside for anything else. It's completely occupied.

Simple Example

Quick Example

Imagine you have a glass of water. If you keep pouring water into it until it cannot hold even one more drop without spilling, then the glass is full. It has reached its limit.

Worked Example

Step-by-Step

Let's say a school bus has 50 seats. --- Step 1: 45 students board the bus. The bus is not full yet because 50 - 45 = 5 seats are still empty. --- Step 2: 3 more students board the bus. Now, 45 + 3 = 48 students are on the bus. Still not full (50 - 48 = 2 seats empty). --- Step 3: 2 more students board the bus. Now, 48 + 2 = 50 students are on the bus. --- Step 4: The bus has 50 students, which is its maximum capacity of 50 seats. So, the bus is now full.

Why It Matters

Understanding 'full' is key in Maths for concepts like capacity, volume, and percentages. In Chemistry, it helps understand how much a container can hold for experiments. In Physics, it relates to density and displacement. Engineers use this daily when designing storage tanks or calculating fuel limits for rockets.

Common Mistakes

MISTAKE: Thinking 'full' means almost full. | CORRECTION: 'Full' means completely full, with no more space. If there's even a tiny bit of space left, it's not truly full.

MISTAKE: Assuming all containers of the same type hold the same 'full' amount. | CORRECTION: The 'full' amount depends on the specific container's capacity. A small glass will be full with less water than a large bucket.

MISTAKE: Confusing 'full' with 'heavy'. | CORRECTION: Something can be full but not very heavy (like a balloon full of air). Something can be heavy but not full (like a half-filled bucket of sand).

Practice Questions

Try It Yourself

QUESTION: A tiffin box can hold 4 rotis. If it has 3 rotis, is it full? | ANSWER: No, because 4 - 3 = 1 roti can still fit.

QUESTION: A petrol tank in a car has a capacity of 40 litres. If it has 35 litres of petrol, how many more litres are needed to make it full? | ANSWER: 40 - 35 = 5 more litres.

QUESTION: A water cooler has a 20-litre tank. If a family uses 5 litres in the morning and 7 litres in the afternoon, how much water is needed to refill it to be full again? | ANSWER: Water used = 5 + 7 = 12 litres. Water remaining = 20 - 12 = 8 litres. Water needed to refill to full = 20 - 8 = 12 litres.

MCQ

Quick Quiz

Which of these describes a 'full' state?

A backpack with some books inside

A bucket with water up to its brim

A plate with one dosa on it

A mobile phone with 50% battery

The Correct Answer Is:

Option B describes a bucket filled to its maximum limit, meaning it cannot hold any more water without spilling. The other options describe items that still have space or capacity remaining.

Real World Connection

In the Real World

When you buy a 1-litre milk packet, it's packed 'full' with 1 litre of milk. When your mobile data plan shows '100% used', it means your daily data limit is 'full'. When a train station platform is 'full', it means there are so many people that no more can comfortably stand there.

Key Vocabulary

Key Terms

CAPACITY: The maximum amount something can hold. | LIMIT: The boundary or point beyond which something cannot go. | OCCUPIED: Filled or taken up. | VOLUME: The amount of space an object or substance occupies.
