## How many formulas are there for volume?

The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units….Volume Formulas of Various Geometric Figures.

Shapes | Volume Formula | Variables |
---|---|---|

Rectangular Solid or Cuboid | V = l × w × h | l = Length w = Width h = Height |

**What is the formula of plane figures?**

Name

Figure | Formula | Nomenclature |
---|---|---|

Triangle | Perimeter: P=a+b+c Area: A=12bh | a,b,c:sides b:base h:height |

Square | Perimeter: P=4a Area: A=a2 | a:side |

Rectangle | Perimeter: P=2b+2h Area: A=bh | b:base h:height |

Circle | Perimeter: P=2πr Area: A=πr2 | r:radius |

**How many plane figures are there?**

There are many kinds of plane shapes, but we will focus on 5 basic kinds: squares, rectangles, circles, triangles, and octagons.

### What are all the plane figures?

The principal geometric plane shapes are:

- The Circle.
- The Triangle.
- The Rectangle.
- The Rhombus.
- The Square.
- The Trapezoid.

**Is volume 2D or 3D?**

3D shapes do have Areas and Volume too since they occupy space. 3D shapes are drawn using X-axes, Y-axes, and Z-axes. A 2D shape has two dimensions- length and breadth. A 3D shape has three dimensions- length, breadth and height.

**What is volume of solid figures?**

The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units 3 units 5 units = 30 cubic units.

## What are plane figures?

Definition of plane figure : a geometrical configuration all of whose points lie in a plane.

**How many planes are there in figure?**

A plane figure is a geometric figure that has no thickness. It lies entirely in one plane.
