This height is called the altitude. It is the amount of distance between the object and the surface of water.
True
False on two counts. A rectangular shape is 2-dimensional and so can have no mass. If it is rectangular but has length, width and height then it is a cuboid object. Then, multiplying the length width and height will give the volume, not the mass.
False because the area of a trapezoid is: 0.5*(sum of its parallel sides)*height
false Actually, the statement is true. You can imagine a 3-d object being made up of a lot of 2-d objects stacked on top of one another. But remember that, by definition, a 2-d object has no thickness (or, in this case, height). Height of one 2-d obect = 0 so height of n such objects = n*0 = 0 So a stack, no matter how many objects you use, will remain 0. And so you are not building up a 3-d object. Alternatively, you could imagine a cube (3-d) being built up from 6 square faces (2-d). Except that this is just the shell of the 3-d object, not the 3-d object itself.

False (apex)
No, the height of an object above sea level is its elevation, not relief. Relief refers to the difference in elevation between the highest and lowest points of a particular area or landform.

Yes, PE=Mgh M=mass g=9.81 H=Height
False, provided the drop occurs no sooner than the throw, and the ground is flat .
false, height is a polygenic trait
false
If both objects have similar air resistance factors, they will both hit the ground together.
