we need to calculate the volume of the pool using the formula for the volume of a rectangular prism. The formula is volume = length * width * height.
Given that the desired volume of the pool is 1400 cubic feet and the length and width of the pool are 20 feet and 10 feet respectively, we can substitute these values into the formula.
So, the equation becomes: 1400 = 20 * 10 * height.
Multiplying the length and width, we have 200 * height = 1400.
To isolate the height, we divide both sides of the equation by 200, which gives us: height = 1400 / 200.
Calculating the division, we find that the height of the pool is 7 feet. Therefore, the pool will be 7 feet deep.
