I suppose they are asking for the ratio of length of the side of cube1 to the length of the side of cube 2.
Take the cube root of each number.  The ratio will be:
cube root of 1728 :  cube root of 19,683.   Simplify the ratio.

The measures of the angles of a triangle are in the extended ratio 4:12:14. What is the measure of the smallest angle?  

6°
24°
72°
84°

ranga · Answer

The three angles of a triangle add to 180 degrees.
The smallest angle will be 4 / (4+12+14) of 180 degrees.

anonymous · Answer

hmmm i dont really understand that :/  if you do 4/(4+12+14) it gets like .133333333

ranga · Answer

Multiply by 180.

ranga · Answer

A better way to do that is:  4/(4+12+14) x 180 = 4/30 x 180 = 4 x 6 = 24

anonymous · Answer

i see. when i multiplied by 180 i got another odd number

anonymous · Answer

but thank you! 
I really needed that help
