Learn How to Calculate the Volume of a Rectangular Prism

In Grade 4, the volume of a rectangular prism is explained as the total amount of space inside a 3D shape, like a box. Think of it as counting how many small cubes would be needed to fill the entire box completely.

• The main idea is to understand that we are measuring a three-dimensional space.
• We use the simple formula l × w × h (length times width times height) for calculation.
• The answer is always written in cubic units, such as cm³ or m³, because we multiply three dimensions.

To find a missing side (length, width, or height) when the total volume is known, you use the volume formula and work backwards with division. First, multiply the two known sides, and then divide the total volume by that result.

For example, if the Volume = 60 cm³, Length = 5 cm, and Width = 3 cm:

1. Multiply the known sides: 5 cm × 3 cm = 15 cm².
2. Divide the total volume by this result: 60 cm³ ÷ 15 cm² = 4 cm.
3. Therefore, the missing height is 4 cm.

A rectangular prism is a very common shape found in many everyday objects around us. These objects have flat surfaces and straight edges, making them perfect real-life examples for understanding volume.

• A shoebox: Used for storing shoes.
• An aquarium: The glass tank that holds water and fish.
• A juice box: A small container for drinks.
• A textbook or a dictionary: A thick book is a rectangular prism.
• A storage container: Plastic boxes used for organising items.

Solving volume problems for Class 4 involves a clear, step-by-step method using the volume formula. Following these steps helps avoid mistakes and makes problem-solving easier.

1. Identify the dimensions: Read the problem to find the values for length, width, and height.
2. Write down the formula: Always start by writing Volume = Length × Width × Height.
3. Multiply the numbers: Substitute the values into the formula and multiply them.
4. Write the final answer: Make sure to include the correct cubic units (like cm³ or m³) in your answer.

Volume and surface area are two different measurements for 3D shapes, but they describe different things. Volume measures the space inside an object, while surface area measures the total area of the outside surfaces.

• Volume: The amount of space an object occupies. It tells you 'how much can fit inside'. It is measured in cubic units (cm³, m³).
• Surface Area: The sum of the areas of all the faces (or surfaces) of an object. It tells you 'how much material is needed to cover the outside'. It is measured in square units (cm², m²).

Yes, this geometry worksheet for Grade 4 is designed in alignment with the learning objectives of the CBSE and NCERT curriculum. The activities, including direct calculation, finding missing dimensions, and real-life problems, support the syllabus requirements for understanding 3D shapes and measurement.

The unit for volume is always 'cubic' because volume measures three-dimensional space. When we calculate volume, we are multiplying three different lengths together.

• Length (measured in cm)
• Width (measured in cm)
• Height (measured in cm)

When you multiply cm × cm × cm, the result is cubic centimetres (cm³). This unit represents a small cube with sides of 1 cm, and the volume tells you how many of these tiny cubes can fit inside the larger shape.
