surface area of a rectangular prism I AM GONNA FAIL :(

Answers

Answer: 99 square cm

Step-by-step explanation:

you cut the height in half, so 6 divided by 2 = 3, if you do that you have to do the same to the width, so again 6 divided by 2 = 3, the length stays the same, so the equation would be 3 X 3 X 11 = 99

Step-by-step explanation:

A contractor is building a set of stairs out of concrete. Each stair is exactly the same length, width, and height.

Staircase
Diagram shows a set of three steps of a staircase. Height of the third step from the ground measures 1.8 meters. The width from the front of the staircase to the back of the staircase measures 1.2 meters. The length of the steps measures 2.4 meters.

Which solid figures can the stairs be broken into? What are the dimensions of each solid figure?

How much concrete will be needed to form the stairs?

Answers

Answer:

Dimensions:

H = 0.9 m

W = 0.4 M

L = 2.4 m

Step-by-step explanation:

As they are all the same dimensions and there are only 3 stairs, divide all the figures (except the length as it will stay the same) by 3 to get your figures.

Answer:

top rectangular prism = .6 x .4 x 2.4

middle rectangular prism = .6 x .8 x 2.4

bottom rectangular prism = .6 x 1.2 x 2.4

concrete needed = 3.672 cubic meters

Step-by-step explanation:

The steps can be broken into bottom step from front to back, middle step from front to back, top step from front to back resulting in

three rectangles

The dimensions of each solid figure can be found since we know the steps are equal so we divide the height and width by 3 equal parts and the length stays the same.  So...

1.8/3=.6 m

1.2/3=.4 m

top rectangular prism = .6 x .4 x 2.4

middle rectangular prism = .6 x .8 x 2.4

bottom rectangular prism = .6 x 1.2 x 2.4

Find the volume by plugging our dimensions into the formula for volume for each step and then add all three steps together for total volume...

.6 x .4 x 2.4= .576

.6 x .8 x 2.4= 1.152

.6 x 1.2 x 2.4=1.944

add totals together...

.576 + 1.152 + 1.944=3.672

Amanda covers the outside of a box, shown in the diagram below, with decorative paper for a school project. The top of the box is open.

If the paper costs $0.03 per square inch what is Amandas total?

Answers

Answer:

C. $4.38

Step-by-step explanation:

To find out how much paper she covers the box with, you need to find the area of each of the rectangles covered by the box.

First, find the area of the side closest to you.

3 x 8 = 24 in^2

Since the side opposite to it is equivalent, they are both 24 in^2, so multiply 24 by 2:

24 x 2 = 48 in^2

Now, find the sides on the left and right (equal in size).

7 x 3 = 21

21 x 2 = 42 in^2

Finally, find the bottom. There is no top, so there's no need to multiply this one by 2.

8 x 7 = 56 in^2

Add up the sides:

56 + 42 + 48 = 146 [tex]in^2[/tex]

Multiply 146 by 0.03:

146 x 0.03 = 4.38

$4.38

Have a nice day!

The answer is c 4.38

A county has the following rule for voting: "Citizens under the age of 18 are not allowed to vote."

Part A: Write an inequality to show the age of citizens who are allowed to vote.

Part B: Describe in words how you can show the solution to this inequality on a number line.

Answers

Answer: Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.

let x = the citizens under the age of 18

x < 18 is your inequality (Part A)

For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).
