To find the total volume of 1.5 × 10^6 sugar cubes, you can multiply the number of cubes by the volume of each cube.
The volume of one sugar cube is 4.9 ml.
So, the total volume \( V \) can be calculated as follows:
\[ V = \text{Number of cubes} \times \text{Volume of each cube} = 1.5 \times 10^6 \text{ cubes} \times 4.9 \text{ ml/cube} \]
Calculating this:
\[ V = 1.5 \times 10^6 \times 4.9 \]
Now perform the multiplication:
\[ 1.5 \times 4.9 = 7.35 \]
So,
\[ V = 7.35 \times 10^6 \text{ ml} \]
Therefore, the total volume of 1.5 × 10^6 sugar cubes is 7.35 million milliliters or 7,350,000 ml.
