Question

A small indoor green house (herbarium) is made entirely of glass panes (including Base) held together with tape. It is 30 cm long, 25cm wide and 25cm high.

Answer 1

Length of glass panes = 30 cm
Breadth of glass panes = 25 cm
Height of glass panes = 25 cm

Total surface area of glass panes' = 2( lb + bh + hl)
2( 30*25 + 25*25 + 25*30)

2(750 + 625 + 750 )

2*2125

4125 Cm square

Tape needed for 12 edges = 4*30 + 4*25 + 4*25
= 120 + 100 + 100
= 320

Answer 2

Heya mate !! here is the answer ✌

Answer:

___________________

Length →30 cm

Breadth→25cm

Height →30 cm

____________________

Total surface area - 2( lb + bh + hl)

=2(30×25 +25×25 + 30×25 )cm²

=2( 750+ 625 +750 )cm²

=2 ×2125 = 4250cm²...

______________________

Area needed for 12 edges ..

4(length+breadth+height)

=> 4(25+30+25) =320cm²....
