Answer:
384 ft²
Step-by-step explanation:
Alrighty! The volume of a cube is V = a³. The equation for the surface area of a cube is 6a². The key number here will come with finding what a is. Here, we are already given the volume: 512 ft³. By working backwards a little we can solve for the variable a using the volume.
Volume = a³
512 = a³
Here we need to isolate the variable a in order to solve for it. In order to do this we must figure out a way to move the cube³ over. We can do this by cube rooting 512!
512 = a³
∛512 = a
The cubed root of 512 = 8 thus:
8 = a
Now we that we have solved for the variable a, we can plug this into our equation for the surface area of a cube.
SA = 6a²
a = 8
SA = 6(8)²
Solving exponents comes first naturally. 8² = 64
SA = 6(64)
SA = 384
Ta-da! Your surface area is 384 ft².

Answer:
The median is 9
Step-by-step explanation:
The median is the number in the middle. The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.
We know that
1 can of soda---------------> <span>40 grams of sugar
if 1 gram sugar------------------------------------>has 4 calories
40 grams (1 can of soda)-----------------------> X
X=40*4=160 calories
then
1 can of soda--------------> has 160 calories
</span><span>six-pack of soda every day--------------> 6*160=960 calories every day
in one year------------> 960*365=350400 calories in one year
if 3500 calories----------------> </span><span>1 pound of fat
</span>350400 calories----------------X
X=350400/3500=100.11 pound
In one year she or he will gains 100.11 pound of fat
the answer is 100.11 pound
Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:
Where the radius of the circle is "r".
You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:
Where "d" is the diameter of the circle.
Then, the radius is:
Finally, substitute the radius into the formula. Then, the area of the circle is:
