What did one geometry book say to the other geometry book?

Don't look at me, I have my own set of problems.

We don't have problems here only solutions.

The type of questions involving volume scale factor can appear problematic.

Honestly there are not.

Let us see.

4 cm 8 cm

Volume 64 cm³ What is the volume of this cube?

1. Find the scale factor of the enlargement 8 ÷ 4 = Scale factor 2

2. THIS DOES NOT MEAN THAT THE VOLUME IS TWICE AS BIG.

3. Take the scale factor and use it as if you were finding the volume i.e 2 x 2 x 2 = 8

4. The volume of the larger cube is 8 times as big

5. 64 x 8 = 512 cm³

6 cm 18 cm

Volume = 60 cm³ What is the volume of this cuboid rectangle?

1. Find the scale factor of the enlargement 18 ÷ 6 = Scale factor 3

2. THIS DOES NOT MEAN THAT THE VOLUME IS THREE TIMES AS BIG.

3. Take the scale factor and use it as if we were finding a volume. 3 x 3 x 3 = 27

4. The volume of the larger cuboid is 27 times as big

5. 27 x 60 = 1620 cm²

__Let us put what we know already into a table__

Scale factor 2 | Volume scale factor 2³ | 4 times as big |

Scale factor 3 | Volume Scale factor 3³ | 27 times as big |

Scale factor 4 | ||

Scale factor 5 |

Scale factor 2 | Volume scale factor 2³ | 8 times as big |

Scale factor 3 | Volume scale factor 3³ | 27 times as big |

Scale factor 4 | Volume scale factor 4³ | 64 times as big |

Scale factor 5 | Volume scale factor 5³ | 125 times as big |

The volume of our skill set is increasing all the time.
