Question

how many soap cakes each measuring 7cm x 5cm x 2.5cm can be placeg in a box of size 56cm x 40cm x 25cm

Answer 1

Answer:

volume of each soap cake=lbh

                                        =7*5*2.5

                                        =87.5cm^3

volume of box=lbh

                      =56*40*25

                       =56000cm^3

therefore no of soap cakes which can be kept in that box=volume of box divided by volume of soap cake

                                     =56000/87.5

                                      =640

Therefore 640 soap cakes can be kept in that box.

Answer 2

-☺☺ HERE IS YOUR ANSWER ☺☺--
___________________________________

length of box = 56cm
breadth = 0.4m = 40cm
height = o.25m = 25cm

Volume of Box = Volume of soap × n
n = number of soaps.
LBH = lbh × n
56 × 40 × 25 = 7 × 5 × 2.5 × n
n = 56×40×25/35×2.5
n = 56000/87.5
n = 640

so, 640 soaps can be placed in the box.
