What are the different terms in solid mensuration?
1. Plane Figures- A flat, closed figure that is in a plane- A plane figure can be made of straight lines, curved lines, or both straight and curved lines.2. Solid Figures- The figures which occupy space are called solids.- Solids are three dimensional figures i.e., they have length, breadth & height.- There are two important facts related to solids-a. Every solid has a surface area. Some solids have plane surfaces, others have curved surfaces.b. Every solid has a 'bulk' & its bulk occupies some space.3. Surface area-It is the sum of areas of all visible (exposed) surfaces of a solid.4. Volume-It is the three dimensional space occupied by a solid, liquid or gas.5. Lateral surface area - is the sum of the surface areas of all its faces excluding the base.6. Total surface area - is the sum of the surface areas of all its faces including the base.
What solid figure rolls and slides?
A cylinder is a solid figure that can both roll and slide. Its shape and symmetry allows it to roll smoothly along a surface, and its circular base provides stability for sliding. Both of these properties make it suitable for applications such as wheels and rollers.
If the surface of a concave mirror is made more curved what happens to its focal length?
A concave mirror is a spherical mirror with a reflective inside surface. When the reflective surface is made more curved, the distance between the focal point and the surface increases. A concave mirror can form both virtual or real images.
Do you count base as one of the faces in a 3d object. Do we also count curved surface as one of the face?
Yes, to both.Yes, to both.Yes, to both.Yes, to both.
What is a shape with a curved face?
A cylinder has two faces that are both curved.
Does a cylinder have a curved and flat surface?
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.

How is a sphere like a cylinder?
Both are 3-dimensional figures wiith a curved surface.
What is difference between a polygon and plane figure?
A polygon is a plane figure with 3 or more straight sides and angles. A plane figure is a flat enclosed figure made of straight lines, curved lines, or both.

A concave mirror is a spherical mirror with a reflective inside surface. When the reflective surface is made more curved, the distance between the focal point and the surface increases. A concave mirror can form both virtual or real images.
What is the difference of curved mirror and flat mirror?
Curved mirrors have a reflective surface that is curved inward or outward, causing light rays to converge or diverge. This allows curved mirrors to form both real and virtual images. In contrast, flat mirrors have a flat reflective surface and only produce virtual images that are the same size as the object.
What does a biconcave shape look like?
Curved in the inner surface on both sides. For example : a red blood cell, crescent moon.
Do you count base as one of the faces in a 3d object. Do we also count curved surface as one of the face?
Yes, to both.Yes, to both.Yes, to both.Yes, to both.
The figure formed by the intersection of a solid with a plane parallel to the base of the solid is congruent to the base if the solid is a?
The answer would be a right cylinder. A right cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base.
Are the laws of reflection applicable to plane surfaces also valid for curved surfaces?
Yes, the laws of reflection are applicable to curved surfaces as well. The angle of incidence is still equal to the angle of reflection, but both angles are measured with respect to the normal at the point of incidence on the curved surface.
How do you figure surface area to volume ratio?
You work both out from measurements of the shape and the relevant formulae.
