If the object hsa sunk the volume is equal to the volume of water displaced
If the tank is 50 cm high, the volume is
150x100x (36.2-30) = 93000 cubic centimeters
Height x Weight x Height
A rectangular prism has a volume that can be found by multiplying the object's length width and height. To obtain the mass one must also know the density of the object and multiply that by the volume.
It is length * breadth * height.
Volume = Length * Width * Height
It is easiest to measure the length, breadth and height and multiply them together.
Height x Weight x Height
Height x Weight x Height
Height x Weight 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.
A rectangular prism has a volume that can be found by multiplying the object's length width and height. To obtain the mass one must also know the density of the object and multiply that by the volume.
the three dimensions needed to find the area of a rectangular solid object are: Height, Length and Width.
Volume = Length * Width * Height.
It is length * breadth * height.
Volume = Length * Width * Height
That task can be accomplished with a ruler, a tape measure, or a measuring cup.
Thermometer
-- measure the length, width, and height of the object -- multiply the three numbers together -- the answer is the volume of the object
