Volume = Length * Width * Height.
the three dimensions needed to find the area of a rectangular solid object are: Height, Length and Width.
water displacement
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.
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.
Volume = Length * Width * Height.
It is length * breadth * height.
Length the width and depth
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.
The answer depends on what part you want the volume for.
Kilogram is weight, not volume.
Partition (or divide) the irregular object into summation of regular objects and then calculate the volume.
Volume = Length * Width * Height
The formula used to calculate the volume of a rectangular solid is: L*W*H=V
Volume= Length X Width X Height
-- measure the length, width, and height of the object -- multiply the three numbers together -- the answer is the volume of the object
Density is weight divided by volume. In the case of a rectangular solid, volume is length times width times height.
