The volume of the corresponding to mass of 3 g is determined as 1.5 cm³.
How to calculate the volume of the object?
The volume of the corresponding to mass of 3 g is calculated by using the following method as shown below;
From the given graph, the mass of the object is plotted on the y - axis (vertical axis), while the volume of the object is plotted on the x-axis (horizontal axis).
At the point where the mass is 3 g on the y-axis, the value of the corresponding volume will be obtained if we draw a line from 3 g to intersect the straight line and trace it down to x - axis.
The value of the volume at 3 g is 1.5 cm³ from the horizontal axis.
