How to Calculate the Volume of Common 3D Shapes

mathantics

In this engaging mathematics lesson, Rob from Math Antics demystifies the concept of volume, starting from the very basics of dimensions. The video builds a clear conceptual foundation by visually demonstrating how a one-dimensional line extends to form a two-dimensional square, which then extends to form a three-dimensional cube. This progression helps students grasp why volume is measured in "cubic" units compared to "square" units for area. The lesson clearly distinguishes between volume (the space inside an object) and surface area (the outer boundary), using a helpful analogy involving a box filled with ice.
