length of side of cube is 1.1 cm and mass of cube is 10.38 g find its volume in view of its significant digits
Answers
These are known as characteristics of a chemical reaction. Let's perform an activity to understand. Take zinc granules in a conical flask and add hydrochloric acid to it and observe. We see that the mixture produces zinc chloride and the temperature of the conical flask is increasing.

The volume of the cube in view of its significant digits is 1.4 cm³.
Given:
The side of a cube is 1.1 cm.
The mass of the cube is 10.38 g.
To Find:
The volume of the cube in view of its significant digits.
Solution:
We are required to find the volume of the cube in view of its significant digits.
The volume of the cube is given as
Volume, V = s³ --------(1)
where s is the side of cube = 1.1 cm
Substitute the value of side(s) in equation(1) we get
V = (1.1)³
V = 1.1×1.1×1.1
V = 1.331 cm³
On rounding off the above answer up to 2 significant figures as the same as the side of the cube.
Volume, V = 1.4 cm³
Therefore, The volume of the cube in view of its significant digits is 1.4 cm³.
