Density=mass/volume or d=m/v and the volume of a cube is s^3
We are given that s=2 and m=10 so
d=10/(2^3) g/cm^3
d=10/8 g/cm^3
d=1.25 g/cm^3
Most of the geometry concepts and theorems that are learned in high school today were first discovered and proved by mathematicians such as Euclid thousands of years ago. Given that these geometry concepts and theorems have been known to be true for thousands of years,
It means logic, where an argument is supported by two premises or propositions.
Given the surface area of the bottom and the volume you can find the height of the box
-3/x is the answer I believe
I hope this helped:)
