Answer:
The volume of the rectangular cistern is 389.76 and area that needs to be covered is 333.92
Step-by-step explanation:
In the question we are basically asked to find the volume of the rectangular cistern and also the total surface area of the same
Now here we are also given the dimensions as
l=11.2m
b=6m
h=5.8m
We know the fomula for volume = l*b*h
and the formula for total surface area of a cuboid will be 2(lb+bh+lh)
putting the values of l,b,h in the above wto formulas we will get
V = 11.2m×6m×5.8m = 389.76 m
TSA = 2(11.2×6 +6×5.8 + 5.8×11.2) m = 2(67.2+ 34.8 + 64.96)= 2×166.96 =333.92m
