## What is the relation between volume and surface area?

## What is the relation between volume and surface area?

The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume.

## Is mensuration and surface area and volume same?

mensuration:— mensuration is defined as the study of the measurement of various 2D and 3D geometric shapes involving their surface areas, volumes, etc. volume :— volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.

**What are the formulas for surface area and volume class 9?**

4. Surface Area and Volume Formulas

Cuboid | |
---|---|

Volume of Cuboid (LSA) | l×b×h |

Lateral Surface Area of Prism (LSA) | p×h |

Total Surface Area of Prism (TSA) | π×r×(r+L) |

l=Length, h=Height,b=Breadthr=Radius of SphereL=Slant Height |

**What is the difference between area and volume class 9?**

The area is the amount of space occupied by a two-dimensional flat object in a plane. Volume is defined as the space occupied by the three-dimensional object. It is always measured in square units. It is always measured in cubic units.

### Why is surface area to volume ratio important?

Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

### Which shape has highest surface area to volume?

The surface area to volume ratio for a cube is 6 to 1 (6:1). Of all the Platonic solids (solids with identical faces) the icosahedron has the lowestsurface area to volume ratio.

**How do you learn surface area and volume?**

Tricks to solve Volume and Surface Area Problems

- Volume = ( r2h) cubic units.
- Curved surface area = (2 rh) sq. units.
- Total surface area = 2 r(h + r) sq. units.

**Which topics comes under mensuration?**

**What are the similarities and differences between area and volume?**

An area is a two-dimensional object whereas volume is a three-dimensional object. The area is a plain figure while volume is a solid figure. The area covers the outer space and volume covers the inner capacity. The area is measured in square units and volume is measured in cubic units.

**What is volume Class 9?**

If an object is solid then space occupied by such an object is measured and termed as the Volume of the object.
