Zraver, I spoke about the area of a target (i.e. a face-to-face projection) am is the area which you see in a sight. The area less, the it is more difficult to you to get in it.
Inclined sheets give more resistance APFSDS and to hollow-charge shells. At identical thickness of sheets, at an inclined leaf of the armour - thickness for penetration of shells
L=Li/sin A
Where: Li - true thickness of a leaf
A - corner of an inclination
Look at tower Merkava:
Thus, you have lacks at direct sheets of the armour.

3BM32 and 3BM39 - are very widely widespread
3BM48 - only on new tanks
3BM52 - it is not enough (still experimentally)
There are two kinds 3BM48:
3BM48 "Svinets" - with uranium (a material "B") the core
3BM48 "Svinets-2" - with the core from a tungstic alloy
Tungstic alloy has some advantages before uranium, but I cannot tell to you about yet it precisely.
