1. Understand the Formula:

* The volume of a rectangular solid (or box) is calculated by: Volume = Length × Width × Height

2. Set up the Equation:

* We know:

* Volume = 650 cubic cm

* Length = 10 cm

* Width = 5 cm

* Height = ? (what we need to find)

* So the equation becomes: 650 = 10 × 5 × Height

3. Solve for Height:

* Simplify: 650 = 50 × Height

* Divide both sides by 50: 650 / 50 = Height

* Calculate: 13 = Height

Answer: The height of the rectangular solid is 13 cm.
