A rectangular-shaped swimming pool is 50m long and 2.5 meters deep and holds 2500 m3 (meters cubed) of water what is the width of the pool? Please explain how you got your answear too please. :)

    I answered your question :Is a rectangle squared or cubed? Apparently you do not care to understand that certain question have no meaning. Fortunately the current one has meaning and can be solved if one remembers the formula for the volume of the swimming pool in terms of length, width and depth (height). Knowing the volume, the depth and the length, one can solve for the width. Know you are ready to do you homework.

Volume = length * depth * width so 2500 = 50 * 2.5 * w
2500 = 125 * w
2500 / 125 = w
20 = w
so it's 20 m wide

Would like to calculate the dimensions of a rectangular pool with a perimeter of 55 meters using decimals only

Let's break down the question to its components.

It is a rectangular pool. It has four sides, with a length and width and the angles in corners being 90 degrees.

Let l be the length of the pool.
Let w be the width of the pool.

The perimeter of the pool is l + l + w + w or 2l + 2w

So 2l + 2w = 55 metres

You could make up a table for all the possible values, starting with a width of 1. 2(1) + 2w = 55
2 + 2w = 55
2w = 53
w = 53 /2

Good luck,

Paul

My pool is 16feet wide by 32 long 10 feet deep what is the square footage

What you looking to know?

Square feet suggests a flat area, like the floor plan of the pool, which would be 16 x 32 = 512 square feet. Like you'd measure walls for tiles or paper etc.

As you've given 3 dimensions, sounds like your after the cubic capacity/volume of the pool, in which case your looking at cubic feet (same as flat area above, but with the added depth to go from flat 2d, to 3d (2 vs 3 dimensions)), which would be 16 x 32 x 10 = 5,120 cubic feet.

How Do I Calculate How Many Gallons Of Water Will Fit In My Pool?

Since 1 cubic foot is equivalent to 7.48051948052 gallons, you could attempt to do the math & make allowances for overflow & for a distance-to-the-top measure of what could be about half a foot. Otherwise, there are charts that help with understanding this.

Can it go into water? i have the casio w-59\590. it's written on the watch water resistant 50M-5 bar

Theoretically means it will resist water penetration to 50 meters. Approx 150 feet deep.
I would not test that limit, but you should be fine in a pool or shower etc..
