Transported 20543

How many cars will the dirt be transported in an excavation 10 m long, 11 m deep, and 70 cm wide if the load capacity of each used
car is 2 tons? The clay density is 1,800 kg/m2.

Correct answer:

n =  70

Step-by-step explanation:

a=10 m b=11 m c=70 cm m=70:100  m=0.7 m  V=a b c=10 11 0.7=77 m3 ρ=1800 kg/m3  m=ρ V=1800 77=138600 kg m1=2 t kg=2 1000  kg=2000 kg  n=m/m1=138600/2000=70
