1. SOLID FIGURES
Visualizing and Describing

2. Learning
Objectives
Visualize and describe solid figures.
Make models of different solid figures: cube, prism,
pyramid, cylinder, cone, and sphere using plane
figures.

3. SOLID FIGURES
Solid Figures are three dimensional objects.
They have three dimensions - length, width, and
height. Being three-dimensional, they take up
space in the universe.
