Learners draw the given shapes to be bigger than they are and find the surface area and volume of each shape. They complete this for two shapes.

Learners calculate the surface area of two cubes given the length of the sides. For the other two diagrams, given the volume of the cube, they determine the measure of the sides. I like the way they move forward and backward with the...

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

Roll right along with an informative lesson that makes cents. Scholars learn that some shapes roll without any change in its width. The video in the Numberphile "Coins" series starts with two-dimensional figures, such as Reuleaux...

Create a solid understanding of the concept of surface area. Building from the previous lesson in the series, the instructor demonstrates how to apply a formula to find the surface area of a rectangular prism. Examples use the formula to...

A regular pyramid has four equal triangular shaped sides and a square base. The lateral area is comprised of the area of the four triangular sides. The surface area is the area of the four triangular sides plus the area of the base....

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

Learn to love the L-shape prism. Viewers of an informative video see how to find the surface area of a composite prism. The method shown finds the area of each side separately and then calculates the sum.

The lateral surface area of a cone. Hmmm, what does that mean? Oh, it means the part you see if the cone was sitting on a flat surface, so it does not include the base. But if you want to include the base then it would be finding the...

Did you know you can use the Pythagorean theorem to find the slant height of a cone? You can! Just watch this tutorial and see how you can find the lateral and surface area of a given cone using slant height and the Pythagorean theorem.
