It is the mass of the block divided by its volume.
You need its mass and volume.
Volume
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
You divide its mass by its volume.
A cuboid or a rectangular prism.
You need its mass and volume.
Volume
on a balance
A triple-beam balance can be used. The units could be g/ml the density of a normal wood is 0.88 but a wood block in density can be anything under 1 so it can be 0.95,0.54,etc. waters density is 1 and would can float on water so wood is anything below 1.

column
The density of an aluminum block typically ranges from 2.63 to 2.70 grams per cubic centimeter.
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
Block A sinks because its density is greater than the density of water, while Block B floats because its density is less than the density of water. Buoyancy force acting on an object is determined by the object's density relative to the density of the fluid it is in.

when a parallel beam hit the rectangular glass it will gave a refraction.
A rectangular group of cells in a spreadsheet can be called a range or a block.
