⎕ | Rectangle | 2 × (length + width) |

▱ | Parallelogram | 2 × (side1 + side2) |

△ | Triangle | side1 + side2 + side3 |

## What are the 3D and 2d surface areas formula?

Area of 3D Shapes Formula

Shape | Surface area | Terms |
---|---|---|

Rectangular prism | 2(wl+hl+hw) | l = length w = width h = height |

Cylinder | 2πr(r + h) | r = radius of circular base h = height of the cylinder |

Cone | πr(r + l) | r = radius of circular base l = slant height |

Sphere | 4πr2 | r = radius of sphere |

**What is the formula for volume of all shapes?**

Volume Formulas of Various Geometric Figures

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

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

Cube | V = a3 | a = Length of edge or side |

Cylinder | V = πr2h | r = Radius of the circular base h = Height |

Prism | V = B × h | B = Area of base, (B = side2 or length.breadth) h = Height |

**What is the volume of all shapes?**

### How do you find the area of shapes?

Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn’t on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).

### How to calculate the volumes of basic shapes?

How to calculate volume Determine which common shape or shapes make up the body. Calculate the volume of each individual common shape using the following equations: If you are calculating the volume of a body composed of several common shapes, simply add the results together.

**What is the formula for all shapes?**

Geometric Shapes Volume = π r 2 h Lateral Surface Area = 2 π rh Top Surface Area = π r 2 Bottom Surface Area = π r 2 Total Surface Area = L + T + B = 2 π rh + 2 ( π r 2) = 2 π r (h+r)

**How do you find the volume of different shapes?**

To find the volume of a shape, apply and solve the right volume formula that correlates with the specific shape in question. Some different shapes might be a cube, cylinder, pyramid or cone.

#### What is the formula for perimeter of a shape?

Write down the basic formula for finding the perimeter of a rectangle. This formula will help guide you as you calculate the perimeter of your own rectangle. The basic formula is: P = 2 * (l + w). Perimeter is always the total distance around the outside edge of any shape, whether it is simple or compound.
