The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube with a surface area of 180 square meters than a cube with the surface area of 120 square meters?

StartRoot 30 EndRoot minus 4 StartRoot 5 EndRoot meters m

StartRoot 30 EndRoot minus 2 StartRoot 5 EndRoot meters m

StartRoot 10 EndRoot meters m

2 StartRoot 15 EndRoot meters m

Step-by-step explanation:

Given,

Where  s = side of the cube

           S A = surface Area

We need to find that how much longer the side of cube having larger surface area.

Solution,

Firstly we will find the side of the cube in each case.

1st case :

S.A. =

Now on applying the given formula for the side 's', we get;

2nd case :

S.A. =

Now on applying the given formula for the side 's', we get;

Now we will subtract from .

Difference =

Hence The side of cube with surface area is longer than the cube with surface area

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
