i think there would be 500 per meter cube instead of 500 per meter square.
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
Length by width by height
length times width times depth
cuboid volume = 49 * 344 * 318 = 5,360,208 cu. cm.>(sphere) volume = 4/3 * pi *r3>radius = cube root ( (3* volume) / (4 * pi) ) = 108.566 cm
40 cubic meters
Since, this is a cubical block, It can be length * breadth* height..
If it is a cubical block, the volume is simply length x height x width.
Assuming it is cut 'square' (not a square shape, but all cuts are at right angles), then the volume is Length x Width x Height
Block being a box: Height * Length * Depth = Volume Giving the three dimensions available.
If its a cuboid, volume = length * breadth * height .
Length by width by height
If you mean the smaller block measures 50cm on all sides - the weight is 900Kg / 8 = 112.5Kg
length x width x height = volume
4096 cm is not a volume, but a length. Once you know the volume, divide the mass by the volume to get the density.
A Belgian block is a nearly cubical block of granite or some other tough stone, used as a material for street pavements.
V = length x width x height
Volume of a rectangular block is: length*width*height. Use consistent units.
