👉 Interstices are a type of mathematical object in geometry that represent the space between two lines or planes, often used to model shapes such as cones and cylinders. They can be thought of as the "gap" between two objects or surfaces. In a 3D coordinate system, an interstice is defined by its position relative to two axes (x-axis, y-axis, z-axis). The coordinates of the point at which this line intersects with one of the axes are known as its x-coordinate
