Same instrument as you would use for a line or perimeter (ruler, measuring tape, etc.). However, you multiply width times length for rectangles and more complicated methods for other 2D shapes. If it's a 3D shape, for cubes/rectangular prisms you multiply length times width time height, and more complicated formulas for other shapes.
Triple-beam balance.
you would use a microdissection instrument
A measuring flask.
The ceilometer instrument.
I would use a thermometer.
You would use a balance or a scale to find the mass of the block in the laboratory. These instruments provide accurate measurements of mass by comparing the weight of the object with a set of calibrated weights.
fill each one with water a see which one holds the most
A measuring cylinder
I would use a thermometer.
