A cylinder is a 3D shape with a circular cross-section and a ... The measurement shown is the diameter of the circular face, so the radius is 3.5 cm. Substituting the values \(h = 16~cm\) and ...

If a rectangular loaf of bread was cut into slices, the shape and size of each slice would be the same. The loaf is very close to being a prism.

Visualizing three-dimensional objects presented on the flat surface of a piece of paper or computer screen is challenging for many of us. For people with math disabilities this sort of spatial ...

Hard as it may be to imagine, there’s a newly defined geometric shape on the books. Based on recent calculations, mathematicians have described a new classification they now call a “soft cell.” In its ...

Dubbed both “soft cells” and “z-cells,” these shapes lack the telltale corners of theoretical math, but still ... cubes and other polyhedral in three-dimensional space are built with ...
