A big showroom is 0.25 million square feet. At the last summer sale, the manager surveyed the showroom to make sure there wasn't overcrowding. The manager found the population density to be 0.003 people per square foot. This included all the people in the building. How many people were in the building on that day?
|
population density = number of people/ square feet 0.003= x/250,000 sq ft
(0.003)(250,000)=x x=750 people A total of 750 people were in the building on that day. |

You are an exporter. You sell cell phones globally. The cell phones are packed in boxes that are 6 inches long, 3 inches wide, and 3 inches high. How many of these boxes can you pack into a big container that is 18 inches long, 12 inches wide, and 15 inches high?

A= lwh
A= (18 in)(12 in)(15in) A= 3240 in³ A=lwh A=(6 in)(3 in)(3 in) A= 54 in³ 3240 in³/54in³=60 boxes |

First find the area of the two triangles:
A=1/2bh A=1/2(15 cm)(40 cm) A= 300 cm² Next, find the area of the rectangle: A=bh A=(50 cm)(40 cm) A= 2000 cm² Next, add the areas of each part together to find the total area of one desk. Triangle 1+Triangle 2+Rectangle= 300 cm² + 300 cm² + 2000 cm² = 2,600 cm². Finally, multiply the area of one desk times 25 to find the amount of wood needed for all 25 desktops. 2,600 cm² * 25 desktops = 65,000 cm² of wood needed. |
