Question

1. list at least two metric units that you used during the measurement activity to represent volume.
2. determine the metric volume of the cube below. remember - a cube is composed of six equal squares.
3. what are the values of the graduations (unmarked lines) in each of the following graduated cylinders? (a) (b) (c)

graduations = __ graduations = graduations = __

Explanation:

Step1: List metric volume units

Common metric - volume units are liters (L) and milliliters (mL).

Step2: Calculate cube volume

From the ruler, the side - length of the cube $s = 2$ cm. The volume formula for a cube is $V=s^{3}$. So $V=(2\text{ cm})^{3}=8\text{ cm}^3$.

Step3: Determine graduated - cylinder graduations

For cylinder (A): The range is from 0 to 5 mL, and there are 5 major intervals. Each major interval is 1 mL, and there are 5 sub - intervals between each major interval. So the value of each graduation is $\frac{1\text{ mL}}{5}=0.2\text{ mL}$.
For cylinder (B): The range is from 0 to 50 mL, and there are 5 major intervals of 10 mL each. Between each 10 - mL interval, there are 10 sub - intervals. So the value of each graduation is $\frac{10\text{ mL}}{10}=1\text{ mL}$.
For cylinder (C): The range is from 0 to 25 mL, and there are 5 major intervals of 5 mL each. Between each 5 - mL interval, there are 5 sub - intervals. So the value of each graduation is $\frac{5\text{ mL}}{5}=1\text{ mL}$.

Answer:

1. Liters (L), milliliters (mL)
2. $8\text{ cm}^3$
3. (A) $0.2\text{ mL}$; (B) $1\text{ mL}$; (C) $1\text{ mL}$
