i)the original cuboid?
ii)the enlarged cuboid?
b) By what ratio has the volume been increased?

Respuesta :

Step-by-step explanation:

a) i) original cuboid = 3×5×2 = 30 cm³......(i)

ii) ratio : 3×2 = 6cm (width), 5×2 = 10 cm (length),

2×2 = 4 cm (height).

enlarged cuboid = 6×10×4 = 240 cm³....(ii)

b) ratio = 240cm³/30cm³ = 8:1.

hope this helps you.
