The volume of a cube is determined by the formula
<span>V=<span>s3</span></span> where s is the measurement of each edge.
Since cube has six square faces, each of the faces will have the area of a square which we know to be <span>A=<span>s2</span></span>. Therefore the total surface area of a cube will be the area of a square multiplied by six (faces).
<span>SA=6<span>s2</span></span>
Solving for the length of edge (side):
<span>V=<span>s3</span></span>
<span>s=<span>3<span>√V</span></span>=<span>3<span>√<span>15625c<span>m3</span></span></span></span></span>
<span>s=25cm</span>
Solving for the surface area:
<span>SA=6<span>s2</span>=6<span><span>(25cm)</span>2</span></span>
<span>SA=3750c<span>m<span>2</span></span></span>
I'm sorry I don't know but you can use photomath you can just download it from the App
Answer:
Part A) The percentage increase was 
Part B) Michael is financially better off this year than last year
Step-by-step explanation:
Part A)
we know that
Using proportion
Let
x-----> the percentage increase
Part B) Compare the percentage increase with the inflation
The percentage increase is greater than the inflation
therefore
Michael is financially better off this year than last year
