Volume
You need its mass and volume.
It is the mass of the block divided by its volume.
A cuboid or a rectangular prism.
I just call it a box or brick or block
This will usually be the case for objects that have different shapes: even if they have the same volume, it is unlikely that they have the same surface area. As an example, calculate the volume and surface area of the following two rectangular block shapes: 1) A 2 x 2 x 2 rectangular block 2) A 1 x 1 x 8 rectangular block
You need its mass and volume.
It is the mass of the block divided by its 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.
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.
You would need a tool called a density meter or a hydrometer to measure the density of a block of wood. This device works by comparing the weight of the wood sample to the volume of water displaced by the wood when submerged. The density of the wood can then be calculated based on these measurements.
To find the density of a block, you would need a scale to measure its mass and a ruler or caliper to measure its dimensions (length, width, and height). Once you have these measurements, you can use the formula Density = Mass/Volume to calculate the density of the block.

Plinth
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.
The mass is 0.72 grams.
