Plot a graph with v on the vertical and t on the horizontal axis

b) To convert the raw volumes $d_i$ (which represent heights) to real volumes $V_i$, we use the provided graph in Fig. 2(b) which plots Volume (cm³) against Height (cm).

Step 1: Read the corresponding real volumes from the graph for each height.

• For $d_1 = 1.0 \text{ cm}$, the real volume is $V_1 \approx 0.5 \text{ cm}^3$.
• For $d_2 = 2.0 \text{ cm}$, the real volume is $V_2 \approx 1.5 \text{ cm}^3$.
• For $d_3 = 3.0 \text{ cm}$, the real
