Given,
Dimensions of the wood block = 10 inch × 6 inch × 2 inch
Mass of the wood block = 3lb
To find,
The density of the wood block in g/cm-³ unit.
Solution,
The dimensions of the wood block
= 10 inch × 6 inch × 2 inch
= 25.4 cm × 15.24 cm × 5.08 cm
[Unit conversion : 1 inch = 2.54 centimetres]
The mass of the wood block
= 3lb
= 1360.77 grams
[ Unit conversion : 1 lb = 453.592 grams]
So,
The volume of wood block
= 25.4 cm × 15.24 cm × 5.08 cm
= 1966.44 cm³ (approx.)
Density
= Volume/Mass
= 1966.44/1360.77
= 1.44 g/cm-³
Hence,the density of the wood block is 1.44 g/cm-³.
