Answer:
The new height of the water is 6.167 m
Step-by-step explanation:
The volume of the pool is given by the product of it's three dimensions width, length and height. In the initial situation we have a pool with width equals 4m, the length equals 6m and height of the water of 2m. So we can find the volume as seen bellow:
initial volume = length*width*height = 6*4*2 = 48 m^3
Then 100 m^3 were added to the pool, so it's new volume will be the sum of the initial volume and the added water so we have:
final volume = initial volume + 100 = 48 + 100 = 148 m^3
Since the only dimension that can change in this situation is the height ofthe water we can use the formula for the volume to find the new height, as seen below:
final volume = length*width*(new height)
148 = 6*4*(new height)
6*4*(new height) = 148
24*(new height) = 148
new height = 148/24 = 6.167 m
The new height of the water is 6.167 m
b for number 1 do u need all of them
49 pieces
First you change the foot into inches, so it is 1200
then you divide so it is 1200/ 24 3/8 = 49 3/13
but the remaining doesn't count since it is not one whole piece
Answer: Take the root of both sides and solve.
h= 0.6, − 0.6
