Question

The trash cans distributed by the city of Mobile are approximately 4 feet tall and have a square cross section with a side of approximately 30 inches. Assuming that the trash can is rectangular, approximate its capacity: 4. a. in gallons b. in metric tons of water at 4°C

Answer 1

Step-by-step explanation:

Length of trash cans = l = 4 feet

Breadth of trash cans = b = 4 feet

Height of trash cans = h = 30 inches = 2.5 feet

1 inches = 0.0833333 feet

Capacity of trash can = Volume of the rectangular trash can = V

V = l × b × h

`V=4 feet* 4 feet *  2.5 feet= 40 feet^3`

a)
`1 feet^3=7.48052 gallons`

`V=40 feet^3=40* 7.48052 gallons=299.221 gallons`

b) Density of water at 4°C = 1 kg /L

1 metric tonne of water = 264.17 gallons of water

`V=299.221 gallons=(299.221)/(264.17)` metric tonne of water

`V=1.1327` metric tonne of water
