Answer:
Dimension of a soap cake =7 cm×5 cm×2.5 cm
Its volume=length×breadth×height=(7×5×2.5) cm
=87.5 cm
Also, the dimension of the box that contains soap cakes is 56 cm×0.4 m×0.25 m i.e., 56 cm×40 cm×25 cm[∵1 m=100 cm]
Volume of the box =length×breadth×height=(56×40×25) cm
=56000 cm
∴ The number of soap cakes that can be placed inside the box =
volume of a soap cake
volume of the box
=
87.5 cm
56000 cm
=640
