one company makes inflatable swimming pools that come in four sizes of rectangular prisms. the length of each pool is twice the width and twice the depth. the depth of the pools are each a whole number from 2 to 5 feet. it the pools are filled all the way to the top, what is the volume of each pool?

Answers

Answer 1

Answer:

Answer:

The volumes of four rectangular prism are 16,54,128,250 cubic feet.

Step-by-step explanation:

Given : One company makes inflatable swimming pools that come in four sizes of rectangular prisms. the length of each pool is twice the width and twice the depth. the depth of the pools are each a whole number from 2 to 5 feet. If the pools are filled all the way to the top.

To find : What is the volume of each pool?

Solution :

Let x be the height of the pool,

The depth of the pools are each a whole number from 2 to 5 feet i.e. 2,3,4 and 5.

According to question,

The length of each pool is twice the width and twice the depth.

So, width = x , length = 2x and height = x

The equation form to find volume is $V=l* w* h$

$V=2x* x* x=2x^3$

Now,

At x=2

$V=2(2)^3$

$V=2(8)$

$V=16\text{ ft.}^3$

At x=3

$V=2(3)^3$

$V=2(27)$

$V=54\text{ ft.}^3$

At x=4

$V=2(4)^3$

$V=2(64)$

$V=128\text{ ft.}^3$

At x=5

$V=2(5)^3$

$V=2(125)$

$V=250\text{ ft.}^3$

Therefore, The volumes of four rectangular prism are 16,54,128,250 cubic feet.

Answer 2

Answer: The equation to find out the volume in this case is V=x*x*2x, or V=2x^3. Use this we can get that the volumes would be 16, 54, 128, and 250.

How many fourths in 4 1/4

Answers

14 fourths, because since 4 fourths make up 1, we would multiply 4 times 4, which gives us 16, and then add the extra 1/4. =)

To determine the number of fourths there are in 4 1/4. Remember that 1+1+1+1 equals 4. Each of the 1's can be written as 1/4+1/4+1/4+1/4. And because 1 = 4 1/4's. Then 4 1's = 16 1/4's. But remember these 16 1/4's are only for the number 4. You must also add the one more 1/4. Altogether there are 17 1/4's present. An easier way to think of this is to convert 4 1/4's into an improper fraction. To determine the number of fourths or 1/4's are present in 4 1/4.
