For the model to be to scale the ratio of the height to the side length should be the same for both the actual pyramid and the model. Is the model of Khufu's pyramid to scale? If not is it close? It’s Part D- Unit Activity-Roots.

I also need help with Part E.

Please help.

Step-by-step explanation:

Scale Model of the Great Pyramid

You can build a model of the Great Pyramid, but first you need to scale it down. To do this, you will need to

make the pyramid 3,000 times smaller than it really is! To achieve that, every 30 meters of the pyramid is

represented as 1 centimeter.

Object

Actual

Height

Scale

Height

(1 cm =

30 m)

Object

to represent

scaled-down

height

Great Pyramid 146.5 m 4.9 cm paper pyramid

Statue of Liberty 92 m 3 cm small paper clip

Sears Building 443 m 14.8 cm ball-point pen

Average person 1.7 m .05 cm (.5 mm) grain of salt

Eiffel Tower 300 m ? ?

Leaning

Tower of Pisa 55 m ? ?

Try finding the scale heights for other objects, such as the tallest building in your neighborhood, your home, or

your height. To do this, divide the object's height in meters by 30 to get its scale height in centimeters. Then

find an object to represent it next to your paper pyramid.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

$a=9\times 12=108\text {ft^2}$

so the area of the floor is 108 square feet, converting that into square yards we get,

$108 \times 0.1111= 12 \text{yd^2}$

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

$\$15 \times 12=\$180$

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

$a = 12 \times 15=180\text {ft}^2$

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

$180 \times 0.111=20 \text {yd}^2$

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

$\$15 \times 20= \$300$

so, it will cost $300.
