Answer 1

Answer:

Jordan needs 3,800\ cm^23,800 cm

2

of carpet to cover the surface area of the post

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The surface area of a prism is equal to

SA=2B+PhSA=2B+Ph

where

B is the area of the base of the prism

P is the perimeter of the base of the prism

h is the height of the prism

Find the area of the base B

B=10^2=100\ cm^2B=10

2

=100 cm

2

Find the perimeter of the base P

P=4(10)=40\ cmP=4(10)=40 cm

we have the height h

h=90\ cmh=90 cm

substitute the values

SA=2(100)+40(90)SA=2(100)+40(90)

SA=3,800\ cm^2SA=3,800 cm

Answer 2

Answer: 3,800

Step-by-step explanation:

the shape of the longer side is 900 because 90*10=900 then there are 4 of those sides so 900*4=3,600

Then for the top of the 3d shape is 100 because 10*10= 100 then its the same for the bottom which is also 100 then add the top and bottom together and you get 200

Then add 3,600 with 200 to get 3,800

So therfore the answer is 3,800 centimeter square.
