Question

The Yogurt Packaging company is now re-designing their factory. They are going to construct a building in

the shape of a square box. Their contractor has told them that the diagonal braces needed to make the roof
are 150 feet long.(please help)


1. What would be the floor plan of the building? Label the diagonal braces



2. Find the dimensions of the new factory



3.Find the perimeter of the new factory


4.the yogurt machines will be placed along the wall of the new factory . Each machine is 10 feet wide.

Find the company fit 40 of the machines in the building Why or Why not ?

Answer 1

1. see attached diagram

2. The dimensions are 75 sqrt(2) by 75 sqrt(2) ft

3. The perimeter is 300 sqrt(2) ft

4. cannot fit 40 machines along the walls

Explanation:

We are using a top down view. We have a square building with side length s. The diagonal is 150 ft

Using the Pythagorean theorem

s^2 + s^2 = 150^2

2s^2 = 22500

s^2 =11250

Taking the square root of each side

sqrt(s^2) = sqrt(11250)

s = sqrt(6225*2)

s = 75 sqrt(2)

The dimensions are 75 sqrt(2) by 75 sqrt(2) ft

The perimeter of a square is given by

P = 4s = 4(75 sqrt(2)) =300 sqrt(2) ft

The perimeter is 300 sqrt(2) ft

Assuming the machines are square ( that they are as wide as they are long) 75 sqrt(2) is approximately 106 ft so you can fit 10 along the wall

Putting them along the top and bottom walls = 20 machines

We are only left with 86 ft along the side walls

86/10 = 8 machines

machines * 2 walls = 16

We can fit 20+16 machines = 36 machines not 40
