Across
- 1. Distance from the center to the circumference of a circle.
- 3. The total area of the surface of a three-dimensional object.
- 5. A 4-sided flat shape with straight sides where all interior angles are right angles (90°) and opposite sides are parallel and of equal length.
- 6. A 3-sided flat shape with straight sides.
- 7. A solid object where the sides are triangles which meet at the top (the apex), and the base is a square.
- 8. The amount of 3-dimensional space something takes up.
- 9. A 2-dimensional shape made by drawing a curve that is always the same distance from a center.
- 12. The distance around a two-dimensional shape.
Down
- 1. A solid (3-dimensional) object which has six faces that are rectangles.
- 2. The distance around the edge of a circle (or any curvy shape).
- 4. A property of an object, i.e. length, width, and height.
- 7. A flat shape with 4 straight sides where all sides have equal length, and every interior angle is a right angle (90°)
- 9. A solid (3-dimensional) object that has a circular base joined to a point by a curved side.
- 10. The measurement of a surface.
- 11. The distance from one point on a circle through the center to another point on the circle.
