In this lesson, young scholars will be required to generate a formula for volume of a rectangular prism. Students working in cooperative groups will use prior knowledge for finding area of a rectangle to determine the "amount of area in...

This calculator finds the volume, surface area, and height of a triangular prism. Surface area calculations include top, bottom, lateral sides, and total surface area. Height is calculated from a known volume or lateral surface.

This online calculator will calculate the 3 unknown values of a sphere given any 1 known variable including radius r, surface area A, volume V and circumference C. It will also give the answers for volume, surface area, and circumference...

Use this calculator to calculate unknown variables for a cube such as a side length, face diagonal, solid diagonal, surface area, and volume.

This online calculator will calculate the various properties of a capsule given any 2 known variables including radius r, side length a, surface area S, volume V and circumference C.

This personal site from Math2.org gives formulas for the area, volumes and surface areas of various shapes. Also provides diagrams.
