📚 Topic Summary
Volume is the amount of space a three-dimensional object occupies. For rectangular prisms (like boxes), you can find the volume by multiplying its length, width, and height. Remember to use the same units for all measurements! Volume is measured in cubic units, such as cubic inches (in³) or cubic centimeters (cm³).
Let's say you have a box that is 5 inches long, 3 inches wide, and 2 inches high. To find the volume, you would multiply these measurements: $5 \text{ inches} \times 3 \text{ inches} \times 2 \text{ inches} = 30 \text{ cubic inches}$ or $30 \text{ in}^3$.
