The term for the measure of space inside a solid shape is "volume." Volume quantifies how much three-dimensional space an object occupies and is typically measured in cubic units, such as cubic centimeters or cubic meters. Different shapes have specific formulas for calculating volume, such as length × width × height for rectangular prisms or (4/3)πr³ for spheres. Understanding volume is essential in various fields, including mathematics, engineering, and science, as it helps determine capacities for containers and the physical properties of objects.
