The video tutorial covers various geometry problems involving cones, pyramids, prisms, and cylinders. It explains how to calculate volumes, compare volumes of different solids, and determine base shapes for pyramids. The tutorial also discusses converting a rectangular prism to a pyramid with the same volume and calculating the volume of a cube formed by square pyramids. Additionally, it addresses determining the scale factor for a model based on area comparison.
