Q2 of 94 Page 231

How many soap cakes each measuring 7 cm 7cmx 5 cm x 2.5 cm can be placed in a box of size 56cm x 40 cm x 25 cm?

We know that,

Volume of cuboid = Length × Breadth × Height


Therefore,


Volume of a soap cake = 7 × 5 × 2.5


= 87.5 cm3


Also,


Volume of the box = 56 × 40 × 25


= 56000 cm3


Therefore,


Number of soap cakes =


= 640 units


Hence,


640 cakes of soap can be placed in a box of the given size
