Answer: Volume is the quantity of 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.
Step-by-step explanation:
SI unit: Cubic metre
Other units: Litre, fluid ounce, gallon, quart, pint, ...
In SI base units: 1 m3
Dimension: L3
J = 506
J needs to be isolated so add 263 to both sides. -263 is cancelled out and 263 + 243 is 506.
Hence the answer of 506
The correct answer should be D
6
Like how

= 36
Square root does the opposite.
Edit: my mistake, it is 6
