With this scenario, we will have three supports underneath the concrete block.
This block measures 40 inches by 24 inches by 24 inches in real life. So AB is 40'' and AC is 24'' and BD is 24''. In the drawing, we are looking at the bottom face of the block (24'' by 40'') and the three suppots will be located as follows:
Support 1 is the circle exactly between A and C. (so its 12'' from A and 12'' from C and its located right on the blocks edge.
Support 2 is the circle exactly between C and D. Its located 20'' from C and 20'' from D and, just like support 1, its right on the edge of the block.
Support 3 is located in the corner of the block at point B.

These are my answers (not exact but close)
Support 1 holds 723 lbs.
Support 2 holds 843.145 lbs.
Support 3 holds 433.809 lbs.
I am using the same sort of logic I used last time, but I'm not sure if its still applicable, since the problem is very different.
