To find the total volume in milliliters of 1.5×10^6 sugar cubes, we need to multiply the volume of one sugar cube (4.9 ml) by the number of sugar cubes (1.5×10^6).

Total volume = 4.9 ml * 1.5×10^6

When multiplying numbers in scientific notation, we multiply the coefficients and add the exponents.

Total volume = 7.35 × 10^6 ml

Therefore, the correct answer is C. 7.35×10^6 ml.
Multiply 0.75 by 2.8×10^−5.
To multiply 0.75 by 2.8×10^−5, we multiply the numbers and add the exponents.

0.75 * 2.8×10^−5 = 2.1×10^−5

Therefore, the answer is 2.1×10^−5.
