Okay, so i see that you need help with this question and it says a swimming pool will be 30 feet wide by 100 feet long, being a total of four inch deep.
00:14
I'm sorry, four feet deep.
00:19
Throughout each wall of the pool plus the bottom must be covered by one coat of paint in two coats of waterproof lacquer.
00:31
So one coat of paint and two coats of lacquer.
00:43
A gallon of paint costs 80 square feet and costs, okay, i'm sorry, one gallon covers 80 feet squared and costs $22.
00:59
Okay, that's for the paint.
01:03
And a gallon of lacquer, one gallon, costs, i'm sorry, it covers 25 square feet and costs $35.
01:21
Determine how many gallons of paint and lacquer will be required to coat the pool.
01:28
Use the above specifications and how much will be spent on the paint and lacquer.
01:34
All right, so first of all, we're going to do 100 times 4 and that's multiplied by 2 and then plus 30 times 4 and we're going to do 2 times 30 times 4 plus 100 times 30.
02:04
So that's 2 times 400 plus 2 times 120 plus 30 times 100 is 3 ,000.
02:17
So that's 800 plus 240 plus 3 ,000.
02:25
And so then i have 3 ,000 plus 240 plus 800 and that's 4 ,040 and that's feet squared...
