A list of puns related to "Cayley's ruled cubic surface"
In our D&D game, and due to D&D silliness, we potentially can take about a cubic foot of sun material and put it in our enemy's castle. Trying to help out our DM by getting an idea on the scale of damage this would cause to the deurgar ("evil" dwarves) and possibly an undead dragon inside. I am unsure of the size of the castle but we know it's their main base of operations so would assume it's a large castle.
I have found that the density of the hydrogen at the surface of the sun is 1.408 g/cm^(3) where as normal air is 0.001225 g/cm^(3). So we are talking about 1000x more dense. and the temperature is about 5800K vs 300K for room air. I'm guessing the super heated gas would rapidly expand and cause shockwaves causing quite a bit of damage before the heat burned everything. But the expansion would be limited and the gas would cool as it expanded. So I don't know how to figure how many joules of work would get done here.
Any help would be appreciated.
My 6yo son has autism and is obsessed with watching number blocks videos on YouTube, memorizing their values, and asking me to make/print charts thereof before finally building them in Minecraft.
For the last month or two, he's loved "empty cubes." This video shows an example of "empty cube 9" whose cubic surface area construction requires 386 blocks based on the formula x = (n^3)-((n-2)^3) where n is the length of any side and x is the number of cubes requires to construct the total "empty cube" structure.

He's now moved on to an obsession with hypercubes and has asked me to make a chart for him in Excel to print, but he has now officially exceeded my modest mathematical abilities. My assumption was that x = (n^4)-((n-2)^4) would be correct, which yields a pattern where the second and third values are 16 and 80. However, he is adamant it should be 16 followed by 74, but he cannot calculate any further. He is not verbal enough to explain to me where he's coming up with these figures.
Would anyone here be able to shed light on where I'm going wrong and perhaps provide a proper formula? He would be elated if I could make this happen for him somehow, and Google has not led me to the answer thus far.
Thanks in advance.
I know the SA of a sphere = 4pir^2, and the volume is basically the one that's given in the title, but how do I go from volume to SA??
Please. I've been losing sleep over this.
My book gave this question to me but I have no idea how to approach it. How would you prove something is a ruled surface in the first place?
Hi guys, I'm selling the following items as well as looking for a platinum surface pen. Preferable newer condition with minimal wear on the tip.
-Nintendo Switch Bundle | Bought the switch late December and have only used it less than 10 times. It's in pristine condition, no scratch or dents. Smoke/pet free household.
