most of the world does SI so more people can understand with it in SI units
The idea is to use an international standard - the same units everywhere.
Inches Feet Fluid Ounces Quarts Half-Gallons Gallons Miles Yards
inches
What units? Feet, inches, metres etc?

Linear units, like inches, can't be converted to cubic units. If they could, then you'd be able to calculate your height in gallons.
It depends on the solid, but typically the scientific unit of a solid is grams. SI units are always metric, so that means you would use centimeters or millimeters instead of inches, liters instead of gallons, et cetera.
The answer depends on the units used for the question. Are they 12 inches * 12 inches * 30 inches or are they feet, or metres or miles?
Not only scientists use them; everybody uses most SI units - except in a few countries, such as the United States. As for the reason, it is mainly (1) for standardization. It is convenient for people all over the world to use the same units. Also, there are two other reasons: (2) Conversions are simpler. To convert 17 km to meters, just multiply by 1000 (add 3 zeroes). This can be done in your head. Now, try converting 17 miles into feet! (3) The SI units are interrelated - they form a consistent set of units. This simplifies many formulae.
Cubic inches, cubic centimeters, liters, quarts, and gallons
It depends on the units used for 146: microlitres, litres, gallons, whatever.
