We have :

the legnth ; a

height ; b

depth : c

When we stack them only a will change.

A(a,b,c) = a*b*c

A1(a1 b1 c1 ) = 28 * 20 * 15 = 8.400

A2 (a2 b2 c2 ) = (1.5*x) * 19.3 * 14.2

x ; Equals the time you should stack them.

A2 (a2 b2 c2 ) = (1.5*17) * 19.3 * 14.2 = 6988,53

b and c is constant.

We look if we have these requirements.

b=> b2

20 => 19,3

c=> c2

15 => 14.2

If yes, then we have to look at a.

a=> a

a=> 1.5*x

And since

a=> 1.5*17

28 => 25,5

So the statement is true and everything is fine.
