Answer 2

HEY,,,

HERE IS YOUR ANSWER,,

length of cardboard box (l1) = 1.4m = 140 cm. ...(1m = 100cm)

width of cardboard box (b1) = 75cm

height of cardboard box (h1) = 49 cm

____________________________

length of soap box (l2) = 6cm

width of soap box (b2) = 5 cm

height of soap box (h2) = 3.5 cm

____________________________

Now.,,

Volume of cardboard box = volume of soap box × n

( n = number of soap boxes )

l1 × b1 × h1 = l2 × b2 × h2 × n

140 × 75 × 49 = 6 × 5 × 3.5 × n

n = 140 × 75 × 49/ 6 × 5 × 3.5

n = 4900

so you get,,

4900 numbers of soap boxes can be put into that cardboard box.

HOPE IT HELPS YOU......
