Volume = Length * Width * Height.
the three dimensions needed to find the area of a rectangular solid object are: Height, Length and Width.

If it is a rectangular trapezoidal pedestal: Calculate the area of the base of the pedestal, multiply by the height of the pedestal. If the angles of the pedestal are not 90deg.. i.e. if it is a pyramidal trapezoidal pedestal. Then calculate the volume as you normally would a rectangular trapezoidal pedestal, and subtract the volume of the missing triangular pieces with the formula 1/3 area of base X height.
False on two counts. A rectangular shape is 2-dimensional and so can have no mass. If it is rectangular but has length, width and height then it is a cuboid object. Then, multiplying the length width and height will give the volume, not the mass.
Volume = Length * Width * Height.
It is length * breadth * height.
Length the width and depth
To find the density of a rectangular solid object, you would calculate the mass of the object by multiplying its volume by its density. For an irregular solid object, you would typically measure its mass using a balance and its volume using displacement of water, then divide the mass by the volume to find the density. The main difference lies in how you determine the volume of the object, with rectangular solids having a straightforward formula for volume calculation compared to irregular shapes which require more complex methods.
It all depends upon the shape of the object. For example, the volume of a rectangular prism is lengthxwidthxheight. For an irregular shaped object, one strategy is to immerse the object into a measured amount of water, then measure what is the total volume of water plus object, and subtract the original volume of water.
In finding the density of a rectangular solid object, you can simply calculate it by dividing the mass by the volume using the formula density = mass/volume. However, for an irregular solid object, you may need to use techniques like displacement method or water displacement method to determine its volume before calculating the density.
The answer depends on what part you want the volume for.
Kilogram is weight, not volume.
To find the volume of an object, you typically need to measure the object's dimensions, such as length, width, and height. You then use these measurements to calculate the volume using the appropriate formula based on the shape of the object (e.g., for a rectangular object, volume = length x width x height). A measuring tool, such as a ruler or tape measure, may also be needed.
The formula used to calculate the volume of a rectangular solid is: L*W*H=V
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
Volume = Length * Width * Height
