Which tools would be needed to measure the size and the mass of a block of wood?

To accurately measure the size and mass of a block of wood, you will need the following tools:

1. Ruler or Measuring Tape: A ruler or measuring tape is essential for measuring the dimensions of the block of wood. You can measure the length, width, and height of the block to determine its size in linear units (usually centimeters or inches).

2. Caliper: For more precise measurements, especially if the wood block has intricate details, a caliper can be used. Digital calipers provide even finer measurements, useful for small or complex shapes.

3. Balance Scale: A balance scale is used to measure the mass of the block of wood. It can provide a precise measurement in grams or kilograms. Ensure that the scale is calibrated correctly before use.

4. Digital Scale (Optional): If a balance scale is not available, a digital scale can also be used to weigh the block of wood, as it typically offers a quick and easy way to determine mass.

5. Calculator (Optional): If you need to perform additional calculations, such as finding the volume (length × width × height) or density (mass/volume), having a calculator handy can be beneficial.

Using these tools will allow you to obtain accurate size and mass measurements of the block of wood.
