You need its mass and volume.
Volume
It is the mass of the block divided by its volume.
It is not possible to answer the question. The volume of a rectangular block requires the measure of three lengths - not 2 as given in the question.
A cuboid or a rectangular prism.
I just call it a box or brick or block
Volume
It is the mass of the block divided by its volume.
Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.
on a balance
First determine the volume of the block of copper by multiplying its dimensions. Volume = 8.4cm x 5.5cm x 4.6cm = 212.52cm3 = 210cm3 rounded to 2 sig figs Density = mass/volume = 1896g/210cm3 = 9.0g/cm3
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.
You need a scale to measure the weight and ways to submerge the block and measure the water to determine the volume.
density of aluminum block
It is 472.44 grams.
