Question

ou need to measure three things: 1. a quantity of water 2. the length of a leaf 3. the mass of a small stone Which unit of metric measurement will you use for each one?

Answer 1

Answer: 1. $m^3$

2. m

3. kg

Explanation:

As we know that there are seven fundamental SI units which are used to fine derived units. These are as follows:

1). Mass - Kilogram

2). Length - meter

3). Time - Seconds

4). Electric Current - Ampere

5). Amount of substance - Moles

6). Intensity of light - Candela

7). Temperature - Kelvin

The metric system uses three main units for measuring:

length in meters (m)

mass in kilograms (kg)

volume in cubic meters $m^3$

Thus a quantity of water is measured in units of volume $m^3$, the length of a leaf is measured in units of length meter (m) and the mass of a small stone in kilogram (kg).

Answer 2

Hey mate!
You stuck?

For a quantity of water, milliliters (mL) are used
For the length of a leaf centimeters or millimeters (cm; mm) are used
For the mass of a small stone, gram (g) are used.

Hope this helps! :)
