Question

choose the correct tools for each of the following measurements. the volume of a sugar cube: ruler the volume of an irregular block of metal: ruler graduated cylinder balance

Explanation:

A sugar cube is a regular - shaped object (a cube). To find its volume, we can use the formula \(V = s\times s\times s\) (where \(s\) is the side length). A ruler is used to measure the side length.

For an irregular - shaped block of metal, we use the displacement method. A graduated cylinder is used for the displacement method. We measure the volume of water displaced by the metal block, which is equal to the volume of the metal block. A balance is used to measure mass, not volume.

Answer:

The volume of a sugar cube: ruler.
The volume of an irregular block of metal: graduated cylinder.
