(2) (N-1)b4Dg
(3) 1/2(N2-N)b4 Dg
(4) (N2- N)b4Dg
​

Answer 1

Answer:

n2 b3DG

Explanation:

thethe similar shapes of cubical shape of a b are lying and on grown density of material of slab is d work done by arranging them over the it is caused to into minus 1 by 3 digit answer is equals to 1 into minus b three digit and -1 before Digi 1 by 2 into minus in before desi into minus in before
