Acube has side length aa. the side lengths are decreased to 20% of their original size. write an expression in simplest form for the volume of the new cube in terms of aa.

Volume of cube = 0.0008a³ unit³                        

Step-by-step explanation:

Let the side length of the cube be a units

Now, The side length of the cube is decreased by 20%

So, New side length of the cube = a - 20% of a

⇒ New side length of the cube = a - 0.20 × a  

⇒ New side length of the cube = a - 0.2·a

⇒ New side length of the cube = 0.8·a

Now, volume of the cube is given by the formula : Volume = (Edge)³

⇒ Volume of cube = (0.8a)³

⇒ Volume of cube = 0.0008a³ unit³                        

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial
