Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.
Slope intercept form will help you find the function of the line :) [ y = mx + b ]
at time = 0 (y-intercept) the pool is 72in deep
the pool loses 2 inches of water every 1 hour. or -2/1
so your equation is y = -2x + 72
Good Luck!
The answer is positive 25 and negative 25

Anyway, this is a binomial, not trinomial.
The mean will be 12. To find the mean, add all values and divide by the number of values. 5+19=24, 24/2=12
