10 km/h
Because if you take 35 and multiply it by 2, and take 0.5 and multiply it by 2, you get 70 kilometers in 1 hour. Therefore, 70-60 is 10 km/h
Thats classified government info, I cant tell you that!
Step 1 - Since 3.3mm^3 = 0.0033cm^3, convert that to 3.3x10^-3 cm^3.
Step 2 - Since 1cm^3 = 1x10^-6 m^3, times 3.3 by that. (3.3 x 1 x 10^-6) = 0.0000033
Step 3 - 0.0000033 = 3.3 x 10 ^-6 m^3, which is your answer choice A.
