This week brought us back to a thing as simple as volume and area, but only with a larger formula. The only difficult part about this is remembering the formulas, but other than that you just have to plug in your measurements. When referring to a pyramid we are referring to a right pyramid. The formulas we use for a pyramid is SA(Pyramid)= Area Base + Area of Triangular Faces -V(Pyramid)= 1/3 Abase(h)- SA(Cone)=πr² + πr – V(Cone)=1/3πr²h

And when you are plugging things into these formulas make sure you use your pie button rather then using 3.14, because otherwise your answer may be off.

This week we learned a lot of different methods, as their is a couple different systems that you can convert to and when converting within there is also a couple different methods too. I chose to show you a method of conversions within the metric system because the units are related to each other by factors of ten this allows us to use a method with a number line. It can be difficult to know when to use which methods and how to know when to use what method but the good thing about using the metric system is that we use it in our day to day life here in Canada so if the unit isn’t recognizable you can automatically rule out the fact that it will be a conversion within a single system, instead you will have to use the exact units (not normally whole numbers) to convert to the imperial system. Down below I have shown you how to use one method- the number line to convert from unit to another within the metric system.
