The excavation

The excavation for the city sewer was 38 m long, 2.2 m wide, and 3 m deep.

a) How many cubic meters of soil were dredged
b) How many journeys had to be made by one car when removing the soil, if they loaded an average of 4.5 m of cubic soil on each journey?

Correct answer:

V =  250.8 m3
n =  56

Step-by-step explanation:

a=38 m b=2.2 m c=3 m  V=a b c=38 2.2 3=12545=12545 m3=250.8 m3
V1=4.5 m3  n=V/V1=250.8/4.5=83615=551115=56
