Answer

\text{42.9 tonnes}

3 steps

Identify the daily cement usage and the number of days.
The contractor used 0.557 tonnes of cement each day.
The total number of days is 77.
Calculate the total tonnes of cement used.
To find the total cement used, multiply the daily usage by the number of days.
$\text{Total cement} = 0.557 \text{ tonnes/day} \times 77 \text{ days}$ $\text{Total cement} = 42.889 \text{ tonnes}$
Round the total cement to 1 decimal place.
The second decimal digit is 8, which is 5 or greater, so we round up the first decimal digit.
$42.9 \text{ tonnes}$
