Title: Find the volume

Grade: 4-a Lesson: S1-L5

Explanation: The best way to understand measurement is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

If the length is 5 cm, the width is 3 cm, and the height is 7 cm,what is the volume of the rectangular prism ?

Step 1a

To calculate the volume of a rectangular prism, you need to know the length, width, and height of the prism.

Explanation: Once you have these measurements, you can use the formula:

Volume = Length × Width × Height

Step 1b

Image: If you have an image that shows the dimensions of the rectangular prism, visually determine the length, width, and height of the prism from the image.
Measure: If you have a physical rectangular prism in front of you, use a ruler or measuring tape to measure the length, width, and height directly. Ensure that your measurements are accurate.

Explanation: Here, we are knowing how to calculate the volume of different images.

Step 1c

Calculation: Once you have the length, width, and height, multiply these values together to calculate the volume.
Make sure to use consistent units (e.g., centimeters, inches, etc.) for all three dimensions.
Volume = 5 cm × 3 cm × 7 cm = 105 cm³ .

Explanation: So, the volume of the rectangular prism would be 105 cubic centimeters.
