Calculate the volume and weight, in English or Metric units, for over 40 geometric shapes and a variety of materials. Select from such metals as Aluminum, Cast iron, or Steel, or from such thermoplastics as ABS, Nylon, or Polycarbonate. Typical values for density are provided, but may be changed to accommodate more specific materials. Apr 16, 2007 · You can measure volume of an irregular solid by submerging it in water in a graduated cylinder and seeing how far the water goes up, if it does not dissolve. You can measure the sides of a regular... Volumes of Solids Date_____ Period____ Find the volume of each figure.

Next, expand the cube uniformly in three directions by unequal amounts so that the resulting rectangular solid edges are a, b and c, with solid volume abc. Each of the 6 pyramids within are likewise expanded. And each pyramid has the same volume abc/6.
