28 = 1*2*2*7
so the dimensions could be 1,4,7 or 2,2,7 or 1,1, 28 cm
Depends if you consider the solid with dimensions 1,4,7 to
represent a different model if you let different faces form the base,
up to you to decide.
for the second question, clearly the base has to be 2 by 2 with a height of 7
or a base of 1 by 1 with a height of 28
each problem.
