Shapes All Around: Area, Surface Area, and Volume

Area tells us how much space is inside a flat shape. Surface area is the total area covering a 3D object. Volume is the space inside a 3D object.

Key Formulas

• Area of a Rectangle: \( \text{Area} = \text{length} \times \text{width} \)
• Volume of a Rectangular Prism: \( \text{Volume} = \text{length} \times \text{width} \times \text{height} \)

Why Know This?

These measurements help us figure out how much carpet covers a floor, how much paint is needed for a box, or how much water a tank holds.
