Calculate 81553

The picture puzzle made of wooden cubes weighs 0.792 kg. One cube has an edge length of 4 cm and a weight of 33 grams. Find out how many cubes make up a puzzle and calculate the wood density in kg/m³.

Correct answer:

n =  24
ρ =  515.625 kg/m3

Step-by-step explanation:

m=0.792 kg g=0.792 1000  g=792 g a=4 cm m1=33 g  n=m/m1=792/33=24
V1=a3=43=64 cm3  ρ1=m1/V1=33/64=64330.5156 g/cm3  ρ=ρ1 kg/m3=ρ1 1000  kg/m3=0.5156 1000  kg/m3=515.625 kg/m3=515.625 kg/m3
