To find the total volume of \(1.5 \times 10^6\) sugar cubes, you can use the volume of a single sugar cube, which is about 4.9 ml.
The calculation will be:
\[ \text{Total volume} = \text{Number of sugar cubes} \times \text{Volume of each sugar cube} \]
\[ \text{Total volume} = 1.5 \times 10^6 \text{ cubes} \times 4.9 \text{ ml/cube} \]
Calculating that:
\[ 1.5 \times 4.9 = 7.35 \]
Now, we also need to account for the exponent:
\[ \text{Total volume} = 7.35 \times 10^6 \text{ ml} \]
Thus, the total volume of \(1.5 \times 10^6\) sugar cubes is \(7.35 \times 10^6\) ml.
Therefore, the correct response is:
7.35×10⁶ ml
