When you change the size of a shape by making it larger or smaller, the degree to which you change its size is measured by something called its scale factor. A linear scale factor is simply the size of the enlargement or reduction of a...

In this video, we will determine the surface area of a rectangular prism (or cube).

In this video, the concept of density is explored through a cocktail experiment. Different liquids with varying densities are layered in a glass container, demonstrating how liquids of different densities do not mix. The video also...

In this video, we learn how to use exponents when finding the area and volume of shapes. The teacher explains that for a square, we multiply the side length by itself to find the area. For a cube, we multiply the length, width, and height.

Do you want to know how to calculate the volume of gases? This chemistry video will show you how to do it with simple real world examples. If you know two of these three, you can work out the third: mass in grams, number of moles and...

An introduction to multivariable calculus in the way of double and triple integrals.

In this video, we explain how to determine whether you need to find the area, surface area, or volume of an object by looking at their definitions. We review the concepts of area, surface area, and volume, and provides examples of how to...

We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...

This lecture shows how Algebra is used to solve problems involving mixtures of solutions of different concentrations.

This video, explains how to find the volume of a rectangular prism by developing a formula. Using the example of a moving truck, the teacher demonstrates how to calculate the number of 1 cubic foot boxes that can fit inside the truck....

👉 Learn how to find the volume and the surface area of a cone. A cone is a 3-dimensional object having a circular base and round surface converging at a single point called its vertex (or apex). The vertical distance from the circular...

In this video to learn about the molar volumes of gases, how to calculate this and where this knowledge is needed in everyday life.

In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

What is the formula to calculate the volume of a cone? Given the radius and height, how do you calculate the volume of a cone? Cylinders, Cones and Spheres, Part 4

In this lesson, students will learn how to solve equations involving cubes and cube roots. They will understand the concept of cubing a number, finding the cube root, and the relationship between squaring and square rooting.

Structures seen on the abdominal surface of the diaphragm.

In this video, the teacher helps students solve a standardized math test question by finding the volume of a rectangular prism. Using a reference sheet and the given information, the teacher guides students through the formula for volume...

In this video, we calculate the volume of a cylinder [with example].

In this video, the teacher explains how to find the volume of an irregular 3D solid by recognizing that volume is additive. They demonstrate this concept by breaking down the solid into two rectangular prisms and finding the volume of each.

How to find the volume of a solid of revolution by the method of cylindrical shells.
