Question 1104569
A Pillar is dug into the ground 1 third of its length.


this means 1/3 of the length of the pillar is in the ground while 2/3 is above the ground.


half of the length is in water.


you've got 1/3 of the length in the ground and 1/2 of the length in the water.


the total length of the pillar that is either in the ground or in the water is 1/3 + 1/2 = 2/6 + 3/6 = 5/6.


that means that 1/6 of the pillar is neither in the ground or in the water.


let x equal the length of the pillar.


since 2 meters is neither in the ground nor in the water, then 2 meters represents 1/6 of the length of the pillar.


1/6 * x = 2
multiply both sides of this equation by 6 to get x = 12 meters in length total.


1/3 of 12, or 4 meters, is in the ground.
1/2 of 12, or 6 meters, is in the water.
1/6 of 12, or 2 meters, is not in the ground or in the water.
