To calculate the total volume of \( 1.5 \times 10^6 \) sugar cubes, you can multiply the number of sugar cubes by the volume of one sugar cube.
The volume of one sugar cube is about \( 4.9 \) ml.
So, the total volume \( V \) can be calculated as follows:
\[ V = \text{Number of sugar cubes} \times \text{Volume of one sugar cube} \]
\[ V = 1.5 \times 10^6 \text{ cubes} \times 4.9 \text{ ml/cube} \]
Now, performing the multiplication:
\[ V = 1.5 \times 4.9 \times 10^6 \] \[ = 7.35 \times 10^6 \text{ ml} \]
Thus, the total volume of \( 1.5 \times 10^6 \) sugar cubes is approximately \( 7,350,000 \) ml, or \( 7.35 \times 10^6 \) ml.
