Question

Water has a density of about 62.5 pounds per cubic foot snow has lower density than water but that density can vary greatly. suppose snow that is falling and settling has a density of about 16 pounds per cubic foot. 8 inches of snow has fallen and you have to shovel the sidewalk that is 40 feet long and 5 feet wide. how much snow must be shoveled

Answer 1

`2,133.33\ pounds` or
`2,133(1)/(3)\ pounds`

Explanation:

step 1

Find the volume of the snow

Convert inches to feet

1 ft=12 in

8 in=8/12=(2/3) ft

`V=(40)(5)(2/3)=(400/3)\ ft^(3)`

step 2

Find the mass of the snow

Multiply the density by the volume

`m=(400/3)*16=2,133.33\ pounds`

`2,133.33=2,133(1)/(3)\ pounds`
