Wood cube with edge 11 cm weights 0.753 kg. What weight have 10, 100 and 1000 these cubes?

Result

10:  7.53 kg
100:  75.3 kg
1000:  753 kg

#### Solution:

$m_{10}= 10 m = 10 \cdot 0.753 = 7.53 \ \text { kg }$
$m_{100}= 100 m = 100 \cdot 0.753 = 75.3 \ \text { kg }$
$m_{1000}= 1000 m = 1000 \cdot 0.753 = 753 \ \text { kg }$
