Question

The new pool is 25 meters long, 3 meters deep and 12 meters wide.

To seal the pool, the entire inside surface must be painted with sealant. One galloon of sealant will cover 24 square meters. how many gallons of sealant will be needed to seal the pool?

The club stores water in large tanks that can hold 350 cubic meters of water. How many tanks must be used in order to fill the pool?

Answer 1

i think 900? i don't know. i'm smart but you made this question kind of confusing. sorry, i can't help you. Good luck, though! :)

Answer 2

the area of one side is 25 times 3 =75 +the other side that is 3 times 12 = 36 you add those two sides which is 111 mulitply that times 2 sinces there are 4 sides not 2 and you got 222 add the area of the bottom of hte pool which is 25 times 12 = 300 (assuming there is no slope in the pool ) = 522 sqare meters of paint

522 devided by 24 = 21.75 that is 22 gallons of sealent but get extra you can always return it

now for the water tanks you need to take the lenght times width time height to find the capacity of the pool which is 24 times 12 times 3 = (using a calculator) 864 cubic meters

number of tanks are 864 devided by 350 means you will need 2 full tanks and part of the third tank so you will need 3 tanks (rounding up to the next full tank)

Answer 3

You need the surface area to cover with sealant so:

SA = 25 X 12 (bottom) + 2 x 25 x 3 (long sides) + 2 x 12 x 3 (short sides)

SA = 300 + 150 + 72

SA = 522 m^2 now divide this by 24 m^2 per gallon to get

21.75 gallons, but since you can't buy 3/4 a gallon, you need 22

To find the tanks needed you calculate the volume of the pool.

V = 25 x 3 x 12

V = 900 m^3 now divide this by 350 m^3 per tank to get

about 2.57 tanks, again you can't have .57 tanks so you need 3

Answer 4

You have two numbers you need to first figure out: the surface area of the pool walls and floor and also the volume of water the pool holds.

Once you have the surface area of the pool you can then divide the surface area by the amount of area one can of sealant can hold. then you have the # of cans needed.

Again, once you have the volume of water the pool holds you can divide that number by the number of cubic meters one tank hold and then you get your # of tanks needed to fill the pool.

One last thing, don't forget to always check your units(ex ft^2, ft^3, etc) and have fun punching the numbers.

Answer 5

The pool has 4 sides and a bottom. Of the four sides, two are 3x25 and two are 3x12. The bottom is 12x25. Add their areas:
2x3x25 + 2x3x12 + 12x25 = 522 m²
Divide by 24:
522/24 = 21.75
To completely paint the pool, 21.75 gal of sealant will be needed.

The volume of the pool is 3x12x25 = 900 m³. Divide by 350:
900/350 = 2.57 tanks

Answer 6

So you just want to calculate surface area, excluding the top.
So to get the surface area of a rectangular prism we use:
SA = (2)lw+(2)lh+(2)wd
SA = 2(25x3)+2(25x12)+2(3x12)
SA = 150+600+72
SA = 822cm^2

But then we need to subtract the top part because it isn't a whole rectangular prism.
The top is the same as the bottom area so we subtract that
SA = 822-(25x12)
SA = 522cm^2

Then we divide 522 by 24 to get the number of gallons.
522/24 = 21.75
So we need about 22 gallons with a 1/4 of a gallon left over.

Then we need to figure the volume of the pool to find the number of tanks needed.

So V = lxwxh
= 25x3x12
=900m^3
Then we divide 900 into 350 to find the number of tanks.
900/350 = 2.6 tanks.
So we need approximately 3 tanks with extra water.

Answer 7

What is the volume of the pool
Height x Width x Depth=Volume

Divide the above by 350 Cubic Meter tanks are neede for above

Answer 8

Part I:

Calculate surface area of pool, divide by coating ability of sealant.

SA = 2 sides (25*3) + 2 sides (12*3)+1 bottom (25*12)
SA = 150 + 72 + 300
SA = 522
x gal = 522 m² / 24 m²/gal
x gal = 21.75
So you'd have to purchase 22 gal

Part II: determine volume of pool, divide by tanks
V = l*w*h
V = 25*12*3
V= 900
x tanks = 900 / 350
x tanks = 2.57 tanks
So you'd have to purchase 3 tanks.

Answer 9

No I hate math yet my previous math instructor used to enable us to have math events and that i made cookies interior the shapes of numbers and plus marks and divisions signs and indicators and circumstances signs and indicators and that replaced into exciting, yet my daughter is a consultant!

Answer 10

21.75 gallons of sealant assuming you don't spill or waste any.

2.5714 tanks to fill it

Answer 11

1. 37.5 so, i guess 38.
2. between 2 and 3.
