Cuboid 5

Calculate the mass of the cuboid with dimensions of 12 cm; 0.8 dm and 100 mm made from spruce wood (density = 550 kg/m3).

Correct result:

m =  0.528 kg


a=12 cm m=12/100  m=0.12 m b=0.8 dm m=0.8/10  m=0.08 m c=100 mm m=100/1000  m=0.1 m  h=550 kg/m3  V=a b c=0.12 0.08 0.1=331250.001 m3  m=h V=550 0.001=66125=66125 kg=0.528 kg

You asked for the weight... in physics, weight is expressed in N not kg. You should know this!

Dr Math
Thank you, we have corrected 'weight' to 'mass'.
