0.735 x 10^7 ml
7.35×10^6 ml
7.35 x 10^7 ml
7.35 x 10^5 ml
To find the total volume of 1.5×10^6 sugar cubes, we need to multiply the volume of each sugar cube by the number of sugar cubes.
Volume of 1 sugar cube = 4.9 ml
Total volume of 1.5×10^6 sugar cubes = (4.9 ml) × (1.5×10^6)
When multiplying numbers in scientific notation, we add the exponents and multiply the coefficients.
(4.9) × (1.5) × (10^6) = 7.35 × (10^6)
Therefore, the total volume of 1.5×10^6 sugar cubes is 7.35×10^6 ml.
Answer: 7.35×10^6 ml
