The volume of cube is 343 cubic centimeters. what is the surface area of the cube? show your work.

Answers

Answer 1

Answer: In short, the surface area of the cube is 294cm^2.

To find volume of a cube, a side is multiplied by itself three times. So, we have this so far, let "s" equal a side of the cube... s*s*s or s^3 = volume. But, we have to work backwards to find s. We know the volume is 343 cm^3 and we know to find volume we take a side and multiply it by itself three times, also known as cubing a side.

So, s^3 = 343 cm^3. To find what one s equals, we have to take the cube root of 343. A cube root is the opposite of cubing a side and that's why it works.

Basically, we're trying to find what number times itself three times will equal 343. A cube root of 343 will tell us the answer. So, once we cube root 343, we get 7. This means that 7 is one s or the side length of the cube. Remember, a cube has all equal sides, so 7 is the side lengths for the whole cube.

Now, to find surface area of a cube, the formula is 6*s^2. This means that the side is squared times six. We already know what the side is, 7, and order of operations, PEMDAS, tells us that exponents come before multiplication. So, we have 7^2 which is 49 times 6. 49 * 6 = 294. Hope this helped!

If ?2000 is placed into a bank account that pays 3% compound interest per year,how much will be in the account after 2 years?

Answers

Answer:

The amount after 2 years in the bank will be $3,380.

Step-by-step explanation:

$A=P(1+(R)/(n))^(nt)$

A = Amount after t time period

P = Principal amount

R = Interest rate

n = Number of times interest applied per time period

We have:

P = $2000

R =3%=0.03

n = 1

t = 2 years

$A=\$2000* (1+(0.03)/(1))^(1* 2)$

$A=\$3,380$

The amount after 2 years in the bank will be $3,380.

Answer:

There would be $2,120

Step-by-step explanation:

First figure out what 3% of 2000 is which is 60. Multiply the 60 by 2 to get 120 then add 120 to 2000

A bag contains 10 red marbles, 15 yellow marbles and 5 green marbles. What is the probability of drawing a red or green marble from the bag?

Answers

Probability =

(number of ways it can come out the way you want)
divided by
(total number of ways it can come out).

Total number of ways to draw a marble = 30 (marbles in the bag).

Number of ways it can succeed = 15 (number of red or green ones)

Probability = 15/30 = 1/2 = 50% .

10(red) plus 5(green) equals 15. red plus green plus yellow equals 30 15/30 - 50%

Thompson's market sells a 25 pound bag of happy chow dog food for $15.49 and a 30 pound bag of super chow dog food for $17.39 which brand is the better buy?Explain

Answers

Answer:

The better buy would be super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Step-by-step explanation:

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Super chow is $17.39 for 30 pounds

The price per pound of Super chow=17.39/30=$0.58

Happy chows($0.62)>Super chow ($0.58)

The better buy would be Super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Happy chow is $15.49 for 25 pounds

One centimeter = ________ millimeters.
A) 10
B) 0.10
C) 100
D) 0.01

Answers

Final Answer:

A) One centimeter = 10millimeters.

Explanation:

One centimeter is equal to 10 millimeters. This can be determined by using the conversion factor of 1 centimeter = 10 millimeters. To convert centimeters to millimeters, you simply multiply the value in centimeters by the conversion factor.

For example, if you have 5 centimeters, you can convert it to millimeters by multiplying 5 by 10, which equals 50 millimeters. Similarly, if you have 2 centimeters, you would multiply 2 by 10 to get 20 millimeters.

The conversion from centimeters to millimeters is straightforward and involves a simple multiplication by 10. This is because there are 10 millimeters in 1 centimeter. So, each centimeter is equivalent to 10 millimeters.

So,One centimeter = 10 millimeters.Therefore,the correct option is A.

In summary, the conversion from centimeters to millimeters is achieved by multiplying the value in centimeters by the conversion factor of 10. This results in the final answer of one centimeter being equal to 10 millimeters.
