Concept:A statement is false if it contradicts known mathematical facts about perimeter, area, and volume.
Explanation:- Statements A, B, and C are true. Different shapes can have the same perimeter but different areas, the same area but different perimeters, and many figures can share the same area.
- Statement D claims volume cannot be estimated without knowing dimensions. This is false. Volume can be estimated using water displacement or by approximations even without exact dimensions.
- Therefore, the statement that is not true is option D.
Answer:D. Volume can not be estimated without knowing the dimensions of a figure.
