Answer:
- If the capacity of a rectangular cistern in liters whose dimensions are 11.2m × 6m × 5.8m, then the area of the iron sheet required to make the cistern is 266.72 sq cm.
Step-by-step explanation:
1) Show that
= RHS
Hence proved.
2) The dimensions of rectangular cisterm is 11.2× 6 × 5.8
Volume is given by l×b×h=11.2 × 6×5.8=389.76
Lateral surface of Cuboid is given by 2h(l+b)=2(5.8)(11.2+6)=11.6(17.2)=199.52 sq cm.
The base area is given by l×b=11.2 × 6=67.2 sq. cm.
The total area of iron sheet required is 199.52+67.2=266.72 sq cm.
