Explanation:

(a)


In\: \triangle ABC \&amp; \triangle DEF \\\\</p><p>\frac {AB} {DE} = \frac {40} {48} = \frac {5} {6}...(1)\\\\</p><p>\angle ABC \cong \angle DEF... (each\: 90°)...(2)\\\\</p><p>\frac {BC} {EF} = \frac {30} {36} = \frac {5} {6}...(3)\\\\

From equations (1), (2) & (3)


\triangle ABC \sim \triangle DEF

(By SAS Postulate)

Hence both of the triangles are similar.

(b)

Prism DEF will have greater volume, because length of its sides are larger than that of prism ABC.

6/5 = 1.2 times greater.
