• Quiz 4 - Sandy is building a tiny fence for her fairy garden. She doesn’t want to build too much so she must measure the perimeter of the garden. The garden is built in a perfect square, just as the fairies like it. It has one side that is 34 cm long. What is the perimeter?

A Step-by-Step Example

Example Problem - I hate being sick, but I have a cold. The medicine says I need to take 2.5 mL every 8 hours. How many liters will I need for 24 hours?

Explanation

Step 1 - Planning: We need to start by thinking through everything it is asking us and paying attention to the units of measure that we have and where they need to be when we provide a solution. We should note two things here the units of volume change from milliliters to liters and the units of time (hours) stay the same. So, we will need to convert the volume of the liquid from milliliters to liters at some point.

Step 2 - How Much Medicine: We know that we need to take 2.5 ml every 8 hours. 24 hours divided by 8 hours is 3. This means that we will take 3 doses of 2.5 ml or 7.5 ml (3 x 2.5) total.

Step 3 - Convert Units: We need to answer our final solution in units of liters. We will need to convert 7.5 ml to liters. There are 1,000 milliliters in a liter. This means that we would move the decimal point three places to the left or 0.0075 l.

How to Identify Units of Metric Measures

The metric system of measurements came into existence ever since the people felt the need to systematically measure the magnitude of quantities. There are different metric units to measure different quantities, such as gram is used to measure mass, the meter is used to measure length, etc. To distinguish the units of different quantities is easy, every quantity has been assigned a separate set of units. However, how to identify different units that pertain to a common quantity?

There are cases where a category of a physical quantity can have subcategories to it. For example, the category of distance and space can have three subcategories to it; linear distance or unidimensional length (measuring how long something is), two-dimensional length (often about the area of something), and three-dimensional length that tells the volume of an object. People often find it confusing to identify what type of unit should be applied in each case. Also, every unit is not suitable in any situation.

Addressing the problem of what to use in uni, bi, or tri-dimensional scenarios, a unit raised to the power of one must be used in the case of unidimensional length. For example, a meter or centimeter can be used to measure length. Whereas in the case of measuring area of a figure, meter or centimeter can be raised to a power of two and three in the case of measuring volume. This is how the units of different categories of metric measures are identified.
