Question

How many soap cakes each measuring 7 CM into 5 CM into 2.5 CM can be placed in a box of size 56cm into 40 CM into 25 CM. ​

Answer 1

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
