Step-by-step explanation:
i) Capacity(Volume) = length x breadth x depth
 = 3.2 x 2.9 x 1.5
 = 13.92 m³
In litres, 13.92 x 1000 = 139,20 litres
ii) Capacity(Volume) = length x breadth x depth
 = 2.5 x 1.6 x 1.3
 = 5.2 m³
In litres, 5.2 x 1000 = 5200 litres
iii) Capacity(Volume) = length x breadth x depth
 = 7.3 x 3.6 x 1.4
 = 36.792 m³
In litres, 36.792 x 1000 = 36,792 litres
