A rectangular prism has a length of 20 in., a width of 2 in., and a height of 3 1/4 in. The prism is filled with cubes that have

Answer: 8320 cubes.

Step-by-step explanation:

1. Calculate the volume of the rectangular prism:

$V_1=l*w*h$

Where l is the lenght, w is the width and h is the height.

Substitute values.

(You can convert 3 1/4 to decimal by dividing the numerator by the denominator of the fraction and add this to the whole part: 3+0.25=3.25)

Then:

$V_1=20in*2in*3.25in=130in^{3}$

2. Calculate the volume of a cube:

$V_2=s^{3}$

Where s is the lenght of any side.

Then:

$V_2=(\frac{1}{4}in)^{3}=\frac{1}{64}in^{3}=0.0156in^{3}$

3. To calculate the number of cubes that are needed to fill the rectangular prism (which you can call n) , you must divide the volume of the prism by the volume of a cube. Then:

$n=\frac{V_1}{V_2}=\frac{130in^{3}}{0.0156in^{3}}=8320$ cubes

How can you compare rational and irrational numbers? why might you want to?

Lynna [10]

An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero.

PLEASE HELP WILL GIVE BRAINLIEST. GEOMETRY REFLECTIONS. INCLUDE EXPLANATION. BOGUS ANSWERS WILL BE REPORTED

frutty [35]

we are given point as

(x,y)=(5,7)

translating 3 units to right side

It means we will subtract 3 to x-value

and we get

(x,y)= (5-3,7)

(x,y)=(2,7)

now, it is reflected about x-axis

so, we can change y-value as -y

so, we get our new point as

(x,y)=(2,-7)

now, we have to find it's image reflection

so, we will get

(x',y')=(-7,2).........Answer
