Find volume.

5 ft, 4 ft, 3 ft

60 ft cubed

Step-by-step explanation:

V = l * w * h

3 * 4 * 5

3 * 4 = 12

12 * 5 = 60

V = 60 ft cubed

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
