Cuboid 5

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

Correct answer:

m =  0.528 kg

Step-by-step explanation:

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  ρ=550 kg/m3  V=a⋅ b⋅ c=0.12⋅ 0.08⋅ 0.1=31253​≐0.001 m3  m=ρ⋅ V=550⋅ 0.001=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'.
