Oak timber is rectangular shaped with 2m, 30 cm, and 15 cm dimensions. Its weight is 70 kg. Calculate the weight of 1 dm³ of timber.

Final Answer:

m =  0.7778 kg

Step-by-step explanation:

a=2 m dm=2 10  dm=20 dm b=30 cm dm=30:10  dm=3 dm c=15 cm dm=15:10  dm=1.5 dm  V1=a b c=20 3 1.5=90 dm3 m1=70 kg  m=m1/V1=70/90=0.7778 kg
