Problema Solution
a swimming pool is 20' long and 16' wide. water line is 4.5'. 6000 gallons of water cost $252.00. what are the total number of gallons and how much does it cost?
Answer provided by our tutors
let
l = 20 ft the length
w = 16 ft the width
h = 4.5 ft
the volume of the pool is V = l*w*h
V = 20*16*4.5
V = 1440 ft^3
1 ft^3 = 7.48052 gal
1440 ft^3 = 1440*7.48052 = 10,771.95 gal
6000 gallons of water cost $252.00
let 10,771.95 of water cost x dollars
6000 : 252 = 10771.95 : x
by solving we find
x = $452.52
