Question

Any is 20cm less than a metre what is Anu height ​

Answer 1

Step-by-step explanation:

For bigger box:

Length of the bigger box 20 cm

Breadth of the bigger box =15 cm

Height of thr bigger box =5 cm

So, Total Surface Area of bigger box =2(lb+bh+hl)

=2(20×15+15×5+5×20)

=2(300+75+100)

=2(475)

=950 cm

2

For Smaller box:

Length of the smaller box =16 cm

Breadth of the smaller box =12 cm

Height of the smaller box =4 cm

So, Total Surface Area of smaller box =2(lb+bh+hl)

=2(16×12+12×4+4×16)

=2(192+48+64)

=2(304)

=608 cm

2

Total surface area of 200 boxes of each type =200(950+608)

=200×1558

=311600 cm

2

Extra Area Required =5% of 200(950+608)

=

100

5

×1558×200

=15580 cm

2

So, Total cardboard Required =311600+15580

=327180 cm

2

=

10000

327180

=32.718 m

2

Cost of Cardboard for 1m

2

=Rs. 20

Cost of cardboard for 32.718 m

2

=20×32.718

=Rs. 65.436

Hence, the cost of the cardboard for supplying 200 boxes of each kind is Rs. 65.436.
