  1. 2. – The amount of space occupied by a solid is called its volume.
  2. 3. – The total area covered by the outer surface of a solid is called the surface area.
  3. 5. – A cube is a solid figure having six equal square faces.
  4. 7. – The perpendicular distance between the base and the top of a solid is called its height.
  5. 9. – A cuboid is a solid figure having six rectangular faces.
  6. 10. – A sphere is a perfectly round solid in which every point on the surface is equidistant from the centre.
  7. 11. – The distance from the vertex to any point on the circumference of the base of a cone is called the slant height.
  8. 12. – The area of all side surfaces of a solid, excluding the top and bottom faces, is called the lateral surface area.
  9. 13. – The distance from the centre to any point on the circular base is called the radius.
Down
  1. 1. – A cone is a solid having one circular base and a curved surface meeting at a single point called the vertex.
  2. 4. – A solid formed by joining two or more basic solids is called a combination of solids.
  3. 6. – The sum of the areas of all the outer surfaces of a solid is called the total surface area.
  4. 8. – A hemisphere is half of a sphere formed by cutting it through its centre.
  5. 9. – A cylinder is a solid with two equal circular bases joined by a curved surface.
