Explanation:
It is given that,
Dimension of a solid block of substance is 74.0 cm by 55.0 cm by 29.0 cm
Mass of solid block is 625 kg or 625000 grams
We need to find the density of solution. The mass per unit its volume is called density.
[tex]\rho=\dfrac{m}{V}\\\\\rho=\dfrac{625000}{74\times 5\times 29}\\\\\rho=58.24\ g/cm^3[/tex]
So, the density of solid block is [tex]58.24\ g/cm^3[/tex]. The density of water is [tex]1\ g/cm^3[/tex]. The density of block is more than water. Hence, it will sink.
