## What is the formula of volume?

Let’s learn!

Geometric Shape Name: | Volume Formula: |
---|---|

Cube | Volume = a³ , where a is length of each side. |

Rectangular Prism | Volume = l × w × h , where l is length, w is width and h is height. |

Sphere | Volume = 4/3 πr³ , where r is the radius. |

Cylinder | Volume = πr²h , where r is the radius and h is the height. |

## What are the two options for creating splines in AutoCAD?

A 1-degree spline results in a line; there is no bend. A 2-degree spline results in a parabola; there can be only one bend. A 3-degree spline results in a cubic Bezier curve; there can be two bends.

## How do you calculate 3D volume?

Calculating the volume of your 3D model

- Determine the number of copies you would like of each file.
- Find the total volume of your job by adding the volume of every copy of every part you wish to print.
- Determine the printer/mode you would like to use for your job.
- Multiply the rate for the printer by your total volume.

## What is a fill volume?

The fill portion is the volume between the upper and lower surfaces when the upper surface is below the lower surface.

## How do you calculate cut and fill volume?

The volume between each pair of sections is estimated by multiplying the average cut or fill area of the two sections by the distance between them. Once these volumes have been calculated for each pair of sections the total cut and fill volumes are obtained by adding them all together.
