A prism is completely filled with 2304 cubes that have edge length of 14 cm

Gemiola [76]

All we have to do is find out the volume of all the cubes to get the volume of the prism.

So since cubes are just 3D squares all of their sides are the same.

So for one cube, determining the volume is just 14^3 (length * height * width), which is 2744.

Now we just multiply 2744 by 2304 and we get: 6322176.

And so the answer is 6322176 cm^3.

This can be shown with this equation:
2304 * (14)^3=x

Where x is 6322176.

I hope this helps! (Also if you could give brainliest, I would really appreciate it!)

Find a formula for the function f(x) such that f′(x)=(ln(x))^2/x and f(2)=6

Rzqust [24]

F(x)= ∫ln²x/x dx= ∫ln²xd(lnx) cause d(lnx)= (lnx)'dx=1/x dx
= ln³x/3 +C with C is constant
In addition, we have f(2)=6, so we have 6=ln³2/3+C
or C= 6- ln³2/3
And f(x)= ln³x/3+ 6- ln³2/3
