Answer 1

Answer:

1

Explanation:

three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

2

SI unit: Cubic metre

In SI base units: 1 m3

Other units: Litre, fluid ounce, gallon, quart, pint, tsp, fluid dram, in3, yd3, barrel

Dimension: L3

3

So to cover a larger distance we use km(kilometre) , hm (hectometre) , and dac(decametre). These are called the multiples of Metre. When the distance is smaller , we use Dm (decimetre , cm(centimetre) and mm (millimetre) . These are called the submultiples of Metre
