1.	Small indoor green house is made entirely of glass panes held together with tape It is 30 cm long 25 wide 25 meter high Find surface area of glasspanes
Answer» $\huge{\underline{\sf{\orange{ Solution-}}}}$ Given : ${\sf{l = 30 cm}}$ ${\sf{b = 25 cm}}$ ${\sf{h = 25 cm}}$ i) What is the AREA of the glass? Area of glass = 2(lb + bh + lh) ${\sf{= 2(30\times25+25\times25+25\times30}}$ ${\sf{= 2(750+625+750}}$ ${\sf{ = 2(2125)}}$ ${\sf{\blue{= 4250\:{cm}^{2}}}}$ II) How MUCH of TAPE is needed for all the 12 edges? Length of tape = ${\sf\blue{4(l + b + h) }}$ ${\sf{= 4(30+25+25)}}$ ${\sf{= 4(80)}}$ ${\sf\blue{=320 cm}}$
