Wood lumber

Wooden lumber is 4 m long and has a cross section square with side 15 cm.

Calculate:
a) the volume of lumber
b) the weight of the lumber if 1 m3 weighs 790 kg

Correct answer:

V =  0.09 m3
m =  71.1 kg

Step-by-step explanation:

l=4 a=15/100=320=0.15 V=l a2=4 0.152=9100=9100 m3=0.09 m3
h=790 m=h V=790 0.09=71110=71110 kg=71.1 kg
