Question

can someone help me please?

after you present the plans to the Noethers, Mrs. Noether loves your drawing so much that she wants you to create a similar pool for the family dogs. She wants the dimensions of this pool to be 1/4 the dimensions of the family pool.

Determine the following:

The dimensions for the dog pool that fit the above specifications
The amount of pool liner material that will be needed to completely line the inside of the pool (sides and bottom)
The amount of water that will be needed to fill the pool if the water needs to be 6 inches below the top of the pool

Answer 1

this is what i have for the family pool The pool is 6 feet deep, 20 feet wide, and 20 feet long. It will be able to hold 2400f3 of water because the volume of a rectangle =a x b x c Let's say that the lining costs 200$ per sq foot.I Use L x A to find the surface area of each individual side (we can't use the traditional internal surface area formula because we won't need tiling for the top of the pool, if you want to be able to swim) 20x 6 =120 four sides of the pool so 480 Now the bottom of the pool 20x20=400 880 sqf of tiling is needed. 880 x 200(the cost of the lining) 176,000 dollars of tiling Okay, so how much water will it take to filll up the pool within 6 inches of the top? take 6 inches away from 6 ft. 5.5 feet. 5.5x20x20=2200 sq ft okay, so you need to fill up 2200 sq ft of pool with water.each sqr foot of pool can hold 7.5 gallons of water. 2200 x 7.481 Shes gonna need 16458.2 gallons of water.
