# Volume and surface area

Basic geometry,

Volume and surface area help us measure the size of 3D objects. We’ll start with the volume and surface area of rectangular prisms. From there, we’ll tackle trickier objects, such as cones and spheres.

This course contains 4 segments:

Volume of rectangular prisms

Welcome to the 3rd dimension! [cue spooky music] This tutorial explains how to find volume.

Volume with fractions

Finding the volume of rectangular prisms that have fractional side lengths

Surface area

Learn how to find the total area of the surfaces of 3D shapes. To do this, we wrap 3D shapes in 2D nets.

Volume of cones, cylinders, and spheres

Let's see how to find the volumes of cylinders, spheres and other three dimensional shapes.
