TSA of aluminium box
=2(lb +BH+hl)
therefore,
= 2(15*10 + 10*6 + 6*15)
= 2(150 + 60 + 90)
= 2(300)
= 600m2
now,
Cost of making the aluminium box
= TSA * rate
therefore,
= (600*50)rs
= 30000rs.
=2(lb +BH+hl)
therefore,
= 2(15*10 + 10*6 + 6*15)
= 2(150 + 60 + 90)
= 2(300)
= 600m2

Answer: Rs 15,000
Step-by-step explanation:
Length of the box = 15m
Breadth of the box = 10m
Height of the box = 6m
Therefore,
Total surface area of aluminum box = 2[length x breadth + breadth x height + height x length]
T.S.A = 2[15*10+10*6+6*15]
= 2[150+60+90]
= 2[300]
= 600sqm
Length of the sheet required = 600/2
= 300m
cost of sheet = [300*50]Rs
= 15,000Rs
