Mathematics 10-3 Module 1 Lesson 3

Module 1: The International System of Units (SI)

Lesson Summary

This photograph shows a worker pouring concrete from a truck.

Ordering concrete for a project involves careful planning, measurement, and calculations. The amount ordered may involve adding a small percentage extra. In order to keep costs down and to ensure the job can be completed with the amount of concrete delivered, mathematics, similar to what you explored in this lesson, are a critical component.

In this lesson, you explored these questions:

How are volume and capacity measured in SI?
What are the common units for measuring volume in SI?
How are volumes and capacities described using one unit converted to another unit?

To answer these questions, you examined the relationships among the cubic metre, cubic centimetre, millilitre, and litre. As in the previous two lessons, you discovered these relationships are based on powers of 10; and, to convert among these units you just had to move the decimal to the left or right.

Unit Project

Before you move on to the next lesson, you should progress in completing the SI section of your Unit 1 Project. In your scale drawing, identify a volume that would be appropriate for conversion between measuring systems. For more information about this and later steps in the Unit 1 Project, refer to the Unit 1 Project.
