Pythagorean theorem is a^2 + b^2 = c^2. the hypotenuse is always the longest, so lets plug in the values.
a^2 + 12^2 = 20^2
if we simplify, we get a^2 + 144 = 400
then subtract 400-144 = 256
then find the sq. root of 256 = 16.
the answer is 16 feet
The answer to the thing is 3 pools per each hour
For the volume of this solid, you’re first going to find the area of the front triangle. so base x height divided by 2. for this it would just be 4.5. then multiply that by the side length. so 4.5 x 3.5, which would be 15.75. so your answer would be 15.75 cubic centimeters
