Expert Answer:

let l,b and h be the dimensions of the cuboid.

So

 acc to qn,

bh=8..(i)

lh=18..(ii)

lb=25..(iii)

(we have just taken the  largest value of area  as the area of the base)

from (i) and (ii)

b=8/h

l=18/h

substituting in (iii) we get,

(8/h)*(18/h)=25

(144/h*h)=25

So,

144/25=(h*h)

(12/5)=h

from this you can get l and b and then vol=60 cu cm
