What is the volume of a rectangular prism with a base of 24 square feet and a height of 5.25 feet?

Blababa [14]

Rectangular prism is nothing but cuboid.

Volume of a cuboid = length × breadth × height

Base area = length × breadth

It is given that base area = 24 square feet and

height = 5.25 feet

Now, volume = length × breadth × height

= base area × height

= 24 × 5.25

= 126 cubic feet

Hence, the volume of the rectangular prism is 126 cubic feet.

What is the IQR of 15,19,20,25,25,28,29,30,30,35,37,43

Alexxx [7]

Answer:

IQR = 10.

Step-by-step explanation:

15,19,20,25,25,28,29,30,30,35,37,43

There are 12 numbers in the list so the median is the mean of 28 and 29,

The lower quartile is the mean of the 3rd and 4th numbers and the upper quartile is the mean of the 9th and 10th numbers.

Lower quartile = (20+25) / 2 = 22.5.

Upper quartile = (30 + 35) / 2 = 32.5.

So the IQR = 32.5 - 22.5 = 10.

UNO [17]

Answer:

$\boxed{392in^2}$

Step-by-step explanation:

Hey there!

Well to find SA we need to find the area of the rectangles.

So lets do the top rectangle,

6*6 = 36

Now lets do the the left rectangle,

10*6 = 60

Now lets do the far right one,

6*4 = 24

Now lets do the second highest rectangle,

4*6 = 24

Now lets do the rectangle facing the right side,

6*6 = 36

Now we can do the bottom rectangle,

6*10 = 60

Now lets do the 2 facing front and back,

6*10 = 60

4*4 = 16

60+16 = 76

76*2 = 152

Now we can add everything,

152 + 60 + 36 + 24 + 24 + 60 + 36

= 392 in^2

Hope this helps :)
