Given:
The shape of box is a right triangular prism.
Paper cost = 2 cents per square centimeter
To find:
The cost to cover the entire box.
Solution:
In the given right triangular prism, we have 3 rectangle surfaces and 2 triangular surfaces.
Area of a rectangle is
[tex]Area=length\times width[/tex]
Area of rectangle with length 4 cm and width 3 cm is
[tex]A_1=4\times 3=12\text{ cm}^2[/tex]
Area of rectangle with length 4 cm and width 4 cm is
[tex]A_2=4\times 4=16\text{ cm}^2[/tex]
Area of rectangle with length 4 cm and width 5 cm is
[tex]A_3=4\times 5=20\text{ cm}^2[/tex]
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Area of triangle with base 3 cm and height 4 cm is
[tex]A_4=\dfrac{1}{2}\times 3\times 4[/tex]
[tex]A_4=\dfrac{12}{2}[/tex]
[tex]A_4=6\text{ cm}^2[/tex]
Bottom and top triangular surfaces are equal.
[tex]A_5=A_4=6\text{ cm}^2[/tex]
Now, total surface area of the box is
[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]
[tex]A=12+16+20+6+6[/tex]
[tex]A=60\text{ cm}^2[/tex]
Paper cost = 2 cents per square centimeter
Cost of 60 square centimeter paper is
[tex]60\times 2=120\text{ cents}[/tex]
Therefore, the cost to cover the entire box is 120 cents or $1.2.

A pulley rotates through 107° in one minute. How many rotations does the pulley make in an hour!
The pulley makes rotations per hour.
(Simplify your answer. Round to the nearest whole number.)
Answer:
18 rotations.
Step-by-step explanation:
As there are 360 degrees in a circle, by proportion, the time for 1 rotation
= (360/107) * 1
= 3.364 minutes.
So the number of rotations in 1 hour (60 minutes)
= 60 / 3.364
= 17.83
Number of rotations does the pulley make in an hour is 18.
Here,
A pulley rotates through 107° in one minute.
What is rotations?
The action or process of rotating on or as if on an axis or center.
Now,
As there are 360° in a circle, by proportion;
Time for one rotation = (360/107) x 1
= 3.364 minutes
Hence, number of rotations in 1 hour
= 60 / 3.364
= 17.83
So, Number of rotations does the pulley make in an hour is 18.

The length of a rectangle is 5 less than 3 times the width. What is the length?
Perimeter = 46 inches
Write an inequality or equation, then solve.
Answer:
Let the width of the Rectangle be x inches
Then, length is (3x-5) inches
Perimeter of the Rectangle= 46 inches (given)
According to the above problem,
Equation :---- Perimeter=2(length+breadth)
2{(3x-5)+x}=46
2(4x-5)=46
(4x-5)=46/2=23
4x=(23+5)=28
x=28/4
x=7
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
Answer:
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
