There are some solids whose volumes can be calculated from the lengths of its edges and an appropriate formula. You could use a ruler in such cases. But there are many shapes for which you simply cannot do that.
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
A ruler to find the measures of the edges and a brain to multiply them together.
Measure the length, measure the width, measure the height, and multiply them all together. LxWxH = volume
get a tape measure or a ruler and measure it
To find the density you need the mass and volume and then, density = mass/volume. Given a ruler, you can easily measure an edge of the cube. If that is x units, then the volume is x3 cubic units. However, it is not clear how you find a mass with just a balance. You need some standard weights, but these do not appear to be provided. You are stuck and cannot answer the question.
To determine the density of a block, you can use a balance to measure its mass and a ruler to measure its dimensions. The density of the block can then be calculated by dividing the mass by the volume.
To find the density of a rectangular solid with just a ruler, you would need to measure the length, width, and height with the ruler. Then, calculate the volume by multiplying the three measurements together. Finally, divide the mass of the rectangular solid by the volume to find the density.
A graduated cylinder is used to measure the volume of irregularly shaped objects like rocks because it can provide a more accurate measurement by allowing the water level to rise precisely to the volume of the object when submerged. This method takes into account the irregular shape of the rock, unlike measuring with a ruler which would only provide an approximation of volume based on dimensions.
Ruler
To find the density of an object, you need to measure its mass (using a scale) and its volume (using a ruler, displacement method, or geometric calculations). Density is calculated by dividing the mass of an object by its volume.
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
When the object is a regular, geometric shape.
A ruler is used to measure length and does not account for the height or width of an object, which are necessary to calculate its volume. To find the volume of a paperclip, you need to measure its dimensions in three dimensions using a tool such as a caliper or by using a water displacement method.
To find the density of an object, you need to measure its mass and volume. Then, divide the mass by the volume to calculate the density. The formula for density is density = mass/volume.
