A cubical swimming pool is of side 12m is filled with water up to a depth of 2m. What is the quantity of water in the pool in li
andrezito [222]

Volume is Length x Width x height.

The pool is cubical, so the length and width are the same dimension.

First find the volume of the pool that is filled by water:

Volume = 12 x 12 x 2 = 288 cubic meters.

Now convert cubic meters to liters:

1 cubic meter = 1,000 liters

288 x 1000 = 288,000 liters

2) if s=2.5; x₁= -5; y₁= -6, then the required equation is:

y+6=2/5(x+5).
