Problema Solution
a square water tank 3.5 meters high has a capacity of 40,000 liters. find the length of the sides
Answer provided by our tutors
Let 'x' represent the length of the square's side.
1 l = 0.001 m^3
40,000 l = 40,000*0.001 m^3
40,000 l = 40 m^3
This means the volume of the tank is:
V = 40 m^3
H = 3.5 m the height of the tank
Since V = x^2*H we have:
x^2*H = 40
3.5x^2 = 40
