A cube is a three dimensional figure with all edges equal.
So it length = width = height
The formula to find the volume of a cube is
V = s³.
Here s represents the length of the cube.
In the given question we are given s = 2.1 cm
So the volume of the cube shall be
V = 2.1³
V = 2.1 × 2.1 × 2.1
V = 9.261 cm³
Now this can be rounded off to two decimals as 9.26 cm³
The volume of the required cube is 9.261 cm³ 0r 9.26 cm³
