Question

how many soap cakes each of dimension 7 cm into 5 cm into 2.5 CM can be placed in a box of dimension 56 cm and 40 cm and 25 CM​

Answer 1

Answer: "Soap Dimensions" -

Length = 7 cm

Breadth = 5 cm

Height = 2.5 cm

Volume = lbh = 7 × 5 × 2.5

= 87.5 cm³

"Box Dimensions" -

Length = 56 cm

Breadth = 40 cm

Height = 25 cm

Volume = lbh = 56 × 40 × 25

= 56000 cm³

Now,

No. of soap cakes × Volume of one soap = Volume of box

No. of soap cakes × 87.5 = 56000

No. of soap cakes = 640
