You can't tell the dimensions of a rectangle from its area, or the dimensions of a prism from its volume.
Volume = length X width X height. Therefore, take the cube root of the volume to find all the dimensions
you look at the shape
You multiply all three dimensions. This only applies for prisms. For example, for a prism with sides 3, 5, and 9, you multiply the dimensions (3*5*9) = 135 units cubed.

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 out the density of a coin, you would first measure its mass using a scale, and then measure its volume using displacement method or by calculating the volume based on its dimensions. The density of the coin can be calculated by dividing the mass by the volume.

Well in general, you can find volume if you have the relevant dimensions. It's much easier for simple shapes. For complicated shapes, it's easier to use other methods. Immersing an irregularly shaped object in a graduated cylinder is a very useful method of finding volume.
To find the density of a penny, you would measure its mass using a scale, then measure its volume by water displacement or using a caliper to measure its dimensions. Divide the mass by the volume to calculate the density of the penny.

To find the density of a rectangular solid, first measure the mass of the solid using the balance scale. Then, measure the dimensions (length, width, and height) of the solid using a metric ruler. Calculate the volume of the solid by multiplying the three dimensions. Finally, divide the mass by the volume to find the density of the rectangular solid.
You multiply all three dimensions. This only applies for prisms. For example, for a prism with sides 3, 5, and 9, you multiply the dimensions (3*5*9) = 135 units cubed.
To find the density of your body, you would measure your body's mass using a scale and then calculate your body's volume by measuring its dimensions and using the appropriate formula (e.g., water displacement method). The density of your body is then calculated by dividing the mass by the volume.
