## Task 1 - 020511

During the construction of the Berlin city center, the "House of Teachers" is being built at Alexanderplatz. First, the excavation pit was dug out. About $7100 \mathrm{~m}^{3}$ of soil had to be removed:

a) How many dump truck loads would this have been, if one truck can transport $4 \mathrm{~m}^{3}$ of soil?

b) How long would the "dump truck convoy" have been for the entire transport, if each dump truck is $3 \mathrm{~m}$ long?
a) The total volume of $7100 \mathrm{~m}^{3}$ is to be divided by the loading capacity of a dump truck of $4 \mathrm{~m}^{3}$: $\frac{7100 m^{3}}{4 m^{3}}=1775$.

There were 1775 dump truck loads.

b) Since each truck is $3 \mathrm{~m}$ long, the total length of all trucks is $3 \mathrm{~m} \cdot 1775=5325 \mathrm{~m}$.
