Answer:
We know that volume of cuboid = length × breadth × height Volume of the cistern = 11.2 × 6 × 5.8
= 389.76 m3
= 389.76 × 1000
= 389760 liters.
Area of the sheet that required to make the cistern = total surface area of the cistern we know that total surface area of cuboid= 2(l b + b h + h l)
= 2 (11.22 × 6 + 6 × 5.8 + 5.8 × 11.2)
= 2 (67.2 + 64.96 + 34.8)
= 333.92 cm2
