Let
x--------> the side length of the cube
we know that
[volume of a cube]=x³
[volume of a pyramid]=[area of the base]*h/3
area of the base=x²
h=x
[volume of a pyramid]=[x²]*x/3-----> x³/3
so
[volume of a pyramid]=[volume of a cube]/3
the answer is
[volume of a pyramid]=[volume of a cube]/3
Answer: greater
I hope that was what you were looking for...
Answer:
y= 10 - 1/4x (FOR LIN)
y=20 - 2/3x ( FOR DIEGO)
Y is what you want , 10 or 20 is what you start with .. whatever amount they drink per second you put in front of x which is the amount of seconds .
