That task can be accomplished with a ruler, a tape measure, or a measuring cup.
volume
There is not an instrument designed to measure the volume of a rectangular box. You would use a ruler or tape measure or similar to measure its linear dimensions and a brain to multiply them together.
You do the Mass of the object then, divide the Volume away from it.
A rectangular prism that measures 8.2cm 5cm and 2cm has a volume of 82cm3
If you have a ruler then you could measure the length width and height and then multiply them together. (LWH is the formula)
A rectangle is a 2-dimensional object and cannot have a volume. A [rectangular] cuboid, of dimensions 8*12*24 has a volume = 2304 cubic units.
A micrometer (or micrometer screw gauge) measures the volume of a screw.
you would use a scale to measure the mass and a beaker to measure the volume. i need another tool

The answer will depend on what characteristic of the object is being measured: its mass, volume, surface area, colour, density etc.
a decibel meter.
Volume = Length * Width * Height.
