(V+2) ρ g=(25+5) g ∵ ρ=1 g / cm 3 ∴ V=28 cm 3

Q. A block of wood has a mass of $25 g$ . When a $5 g$ metal piece with a volume of $2 c m^{3}$ is attached to the bottom of the block, the wood barely floats in water. What is the volume $($ in $c m^{3})$ of the wood?

$(V + 2) ρ g = (25 + 5) g$
$∵ ρ = 1 g / c m^{3}$
$∴ V = 28 c m^{3}$

Q. A block of wood has a mass of 25g. When a 5g metal piece with a volume of 2cm3 is attached to the bottom of the block, the wood barely floats in water. What is the volume ( in cm3) of the wood?

(V+2)ρg=(25+5)g ∵ρ=1g/cm3 ∴V=28cm3
