Step-by-step explanation:
dimension=26×26×45
area of tin=TSA
TSAof cuboid =2 (lb+lh+bh)
=2 [(26×26)+(26×45)+(26×45)]
=2 [26 (26+45+45)]
=2 [26 (116)]
=2×3016
=6032sqcm=6.032sq.m
20 cans =6.032×20
=120.64sq.m
rate=rs10/sq.m
total cost =120.64×10
=Rs.1206.4
Answer:
firstly dimensions of the can are 26×26×45.
tsa of cuboid =2(lb+bh+lh)
=2(26×26+26×45+26×45)
=2(676+1170+1170)
=2(3016)
=6032cm²
Or , 6.032m²
so tin sheet used to make 20 such cans=6.032×20=120.64m²
now cost of 1 m² tin sheet = ₹10
so total cost for making these cans =₹(120.64×10)
