Question

a tea box measure 12m×9cm×4cm.how many such boxes can be packed in a cardboard box of measure 0.6m×0.45m×0.8m

Answer 1

Given
length , breadth & height of tea box = 12 m , 9cm , 4cm.
100 cm = 1 m
9cm = 9 /100
4 cm = 4 /100.
volume of tea box = 12×9/100×4/100
= 432 /10000m^3
volume of cardboard box = 0.6×0.45×0.8 m^3
= 0.216 m ^3
no.of box can be packed = volume of cardboard/ volume of tea box.
0.216 / 0.0432 = 5
so 5 boxex can be packed. ans

Answer 2

Answer:

Given

length, breadth and height of a tea box = 12m× 9cm× 4cm

Volume of a tea box = L× B× H

=12m× 0.09m× 0.04m

=0.0432m^3

Volume of cardboard= L× B× H

= 0.6m× 0.04m× 0.8m

= 0.216m^3

Number of such boxes can be packed in cardboard box=0.216m^3 × 10000÷ 0.0432m^3 × 1000

= 5 boxes
