Each small cube has a volume of 1 cm 3. The volume of the cuboid is 12 cm 3. The surface area of a 3D shape is the total area of all the faces. A cube has six faces which are all squares.

A cylinder has 2 flat circular faces and a curved surface. Imagine a tin with a label around the curved surface. Taking the label off the tin and flattening it out gives a rectangle. The length of ...

Note that as the radius of a cell increases from 1x to 3x (left), the surface area increases from 1x to 9x, and the volume increases from 1x to 27x. Eukaryotic cells are more complex than ...

As the side length of the cube increases, both the surface area and volume grow ... with the specific mathematical expressions varying based on the geometry. Nanomaterials with high surface-to-volume ...
