Learning Resources Folding Geometric Shapes Bundle, Math Class Accessories, 3-D and 2-D Concepts, Measurement, Area, Volume and Surface Area, 16 Pieces, Grades 2+, Ages 7+

Hi, I’m Rob. Welcome to Math Antics! In this lesson, we’re going to learn about another important geometry quantity called Volume. Specifically, we’re going to learn what volume is, and what kind of units we use to measure volume, and how we can calculate the volumes of a few simple geometric shapes. The first thing you need to know is that Volume is a quantity that all 3-Dimensional objects have, but to understand what it means, it will help if we back up just a little and start out with a 1-Dimensional object like this line segment. To measure a 1-Dimensional object we need a 1-Dimensional quantity which we usually call “length”. The length of this line happens to be exactly one centimeter (which is a common unit for measuring length). And in the Math Antics video about area, we saw that if we move (or extend) this 1-Dimensional line in a direction perpendicular to it by a distance o
