Volume

We aim to give learners a deeper understanding of the concept of volume and how to estimate, measure and calculate the volume of right prisms. We explain the terminology needed for working with prisms. Then we explore the concept of volume by looking at the amount of space that is taken up by different objects. We use one formula, and apply it to different right prisms and to a cylinder. The first seven lessons consolidate an understanding of volume of right prisms and their formulae that learners may have worked with before. Then we use these tools to address the Grade 10 Assessment Standard in the last two lessons. We estimate, calculate and then generalise the changes to the volume of a right prism when its dimensions are changed. Note that in the video lessons, we use 3,143 for pi and we round off the answers at different steps of the calculation. Your learners will get different answers if they use pi on their calculators and only round off at the end.
