Question

Tin boxes each of size 45 cm x 30 cm x 30 cm are required to pack biscuits. Calculate the area of tin sheets required to make 25 such boxes.​

Answer 1

Step-by-step explanation:

45×30×30=40500cm

hence, for 25 boxes

40500×25=1012500cm

therefore, 1012500 cm (10125 m) tin sheet requre for 25 boxes.

Answer 2

Answer:

solution : Area=2(lb+bh+lh)

=2(45×30+30×30+45×30)

2(1350+900+1350)

=2(3600)

=7200

Area of 25 box= 7200×25=180000cm

180000/10000

Ans=18m²
