If you mean the block is leaning against a wall at 45 degrees.

Let height (and dist of base from wall) = x

Then by Pythagoras' theorem x^2 + x^2 = 4^2

2x^2 = 16

x^2 = 8

x = root 8 = 2.83 feet.

What do you mean by a 4 foot block?

A 4 x 4 square, standing on edge, is 4 * squareroot(2) =5.66

A 4 ft high thing, leaning over by 45 degrees is

4 / squareroot(2) = 0.707

A little under 6 feet.

4 foot divided by the square root of two - approx 1.4 - so the height will be 2.85 foot.
