If its a cuboid, volume = length * breadth * height .
answer 200
120/200 = 3/5 = 0.6 g/cm3
180 grams / 30 cm3 = 6 g/cm3.
you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume
The volume of a solid block is V = length x width x height12.5 x 9.65 x 3 = 361.875 cm3(cubic centimeters)
Since, this is a cubical block, It can be length * breadth* height..
If its a cuboid, volume = length * breadth * height .
40 cubic meters
answer 200
20cm by 20cm by 50cm
300
If the density of the block is less than the density of water, then the block will float. Density of water is close to 1 gram per cubic centimeter. So measure the block and calculate its volume (Length x Width x Height). Use a scale to find the block's mass. Then divide mass/volume to calculate density. If you've measured in grams and centimeters, then the units will be g/cm³, then compare this to 1 g/cm³.
your question is unclear We can make some assumptions though. If you talk about a piece of wood, then the scale is most likely Inches. That would mean that you have a unspecified length of wood that is 6 inches wide and 2 inches thick. If however talking about steel, then the measurement is probably in Centimeters. An unspecified length of steel/iron that is 2 centimeters thick and 6 centimeters wide. This would probably be a hollow length of some material.
