A ruler no a better way is by dropping the cube in a liquid containg beaker displaced liquid will give you the volume
graduated cylindergraduated cylinderSubmerge your solid in a liquid the liquid volume displaced is equal to your irregular solid volume.
L x W x H Lenght x Width x Hieght
If you have a ruler then you could measure the length width and height and then multiply them together. (LWH is the formula)
Density = Mass / Volume. There is not an instrument that will measure both so you will need to measure them separately and calculate the density.
The answer will depend on what characteristic of the object is being measured: its mass, volume, surface area, colour, density etc.
Any measure of length such as a ruler, yard stick, meter stick, tape measure, etc.
To find the volume of an irregular solid, you can use a graduated cylinder and the water displacement method. First, fill the graduated cylinder with a known volume of water and record this level. Then, gently submerge the irregular solid in the water; the rise in water level indicates the volume of the solid, which can be determined by subtracting the initial water level from the new water level. This method effectively measures the volume of the solid without needing its dimensions.
270 cubic inches
Milliliters and liters are units of volume.
3456 square yards
Spheres are measured with solid angles (which are like two dimensional angles). These angles can be measure with square degrees or steradians. A sphere measures 129300/π square degrees (or about 41,253 square degrees). A sphere measures 4π steradians (or about 12.566 steradians.)
There is no "space" inside a solid figure (body).However the solid figure can be measured in terms of its volume (the amount of space it occupies).
