Answer 1

Area of four walls are 0.4 sqm , 0.4sqm, 0.5 sqm , 0.5sqm

Answer 2

Answer:

Step-by-step explanation:

Given that

Box dimension are

1 m,  80  cm,  50  cm

Now,

l×b×h=1 m×80 cm×50 cm

We know that.                                                                

1 mtr=100 cm.

l×b×h=100 cm×80 cm×50 cm    

Then,                                                                

l=100 cm

b=80 cm

h=50 cm

We know that.

Area of four walls                                                              

 =2 h (l+b)

=2×50(100+80)

=100×806

=18000 cm  sq

 

  Hence, this is the answer.
