Question 1026045
all areas of a cube increase by a factor of 3/2. how many times greater is the surface area.
It's 1.5 times the area (given).
That's 0.5 times greater, or 50% greater.
-----------
how many times greater is the volume?
Area is a function of the square of the edge length.
(3/2)x area --> sqrt(3/2) edge length.
---
Volume is a function of the cube of the edge length.
--> Volume is increased by a factor of {{{(3/2)^(3/2)}}}
= Vol is {{{3sqrt(6)/4}}} times the original volume.
--> an increase of {{{(3sqrt(6) - 4)/4}}}
======================================
PS  x times greater = (x+1) times as great.
-----
eg
Vol is 4x greater --> Vol + 4*Vol = 5*Vol
