Question

a small green house [herbarium] is made throughout of glass panes [including base ] held together with tape. its 30cm long, 25cm wide nd 25 cmhight . find (1) what is the area (2) how much tape is needed for all the 12 edges ?

Answer 1

Answer:

Step-by-step explanation:

Area=Tsa of the cuboid

=2(lb+bh+lh)

=2(30*25+25*25+30*25)

=2(750+625+750)

=2(2125)

=4250

So area is 4250cm^2

Now,length of tape needed for all 12 edges

=(perimeter of the top)+(perimeter of the bottom)+(4 vertical edges)

=4(l+b+h)

=4(30+25+25)

=4(80)

=320 =3m 20cm

So the length of tape required for all 12 edges is 3m20cm
