Length of tank(L) = 12m
Breadth of tank(B) = 8m
Height of tank(H) = 6m
Area of base = L×B=12×8= 96 m2
Area of lateral surface = 2(L×H + B×H)=2(12×6 + 8×6) =240 m2
Area of lateral surface = 2(L×H + B×H)=2(12×6 + 8×6) =240 m2Total suface area of the open tank = 240 + 96 =336 m2
Thus, Area of Iron sheet reqd. = 336 m2
Width of iron sheet = 4mLength of iron sheet =Area/ Width
=336/4=84 mCost of 1 m of iron sheet = Rs 17.50Cost of 84 m of iron sheet = Rs 17.50 × 84 =Rs 1470
