Seventh graders will extend their knowledge of volume to find the volume of right prisms, seeing that the volume is the area of the base multiplied by the height.

Students will investigate the relationship between surface area and volume and their application to the inner workings of real life organisms.

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Use this calculator to determine the volume, surface area, or other figure for a square pyramid, given the other numbers. Users set their parameters for two known variables of the pyramid and find what the unknown amounts would be.

Explains how to calculate the volume and surface area of a cylinder using the standard formulas. Includes example problems.

Geometry is the study of how to use math to describe and investigate different points, lines and shapes. The way that a shape is described in geometry is with a formula, which is simply a mathematical way to calculate different...

Use this interactive tool to explore cones. Change the height and the radius to see how these affect the cone. There is also the option of making an oblique cone. Properties of a cone are discussed, how to use formulas to calculate the...

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a...
