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.
To calculate the density of the rectangular block, first determine its volume using the formula: Volume = length × width × height. Here, the volume is ( 8 , \text{cm} \times 6 , \text{cm} \times 5 , \text{cm} = 240 , \text{cm}^3 ). Density is then calculated by dividing the mass by the volume: Density = mass/volume = ( 500 , \text{g} / 240 , \text{cm}^3 \approx 2.08 , \text{g/cm}^3 ).
You divide its mass by its 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.

Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
The density of an aluminum block typically ranges from 2.63 to 2.70 grams per cubic centimeter.
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.
Weigh the blockcalculate the volume of the block. This is done by measuring the length, height, and width of the block if it is rectangular. If it is some other shape then other mathematical formula apply. If it is an irregular shape for which no formula exists then you can estimate the volume by incremental methods or by displacement.divide weight by volume.
