Answer:
Answer: 216 cm2 (square centimetres 
, in your question you had to put cm3, cubic centimetres, it's IMPORTANT )
Step-by-step explanation:
A perfect cube by definition has 3 equal dimensions, as an immediate rule: volume and total surface are equal, only the unit of measure changes (cubic for the volume, square for surface).
But let's calculate it anyway:
Volume = Edge * Edge * Edge = length * width * depth = 
(remember: all edges are equal in this case)
so Edge = ![\sqrt[3]{Volume}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BVolume%7D)
in your example Edge = ![\sqrt[3]{216}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D)
= 6cm
So the surface of one side is 6*6 = 36
There are 6 sides in total, so the total surface is 6*36 = 216
Note: I call them "edges" but in case of a cube most say just "length"
If it's like the in and out things, I think i can help. So a number goes in and and comes out. What is the rule? What happened from the in to the out?
Z would have to be 4. Cause it's reverse squared. So 4^-2 would be 1/16 but its 4^-3 so it's 1/64.
Answer:
I don’t know which answer choice it is since C and D are the same but the answer is supposed to be x < -15.
