The correct answer is B. 2.8 x 10-7

To find the value of \((0.006)^3 + (0.004)^3\) in standard form, we'll perform the calculations and then convert the result to standard form.

Let's calculate the cubes of \(0.006\) and \(0.004\):

\((0.006)^3 = 0.000000216\)

\((0.004)^3 = 0.000000064\)

Now, add the two results:

\(0.000000216 + 0.000000064 = 0.000000280\)

To express this value in standard form, we'll write it as \(2.80 \times 10^{-7}\).
