Question

Find the capacity of a rectangular cistern whose length is 6m, breadth is 5m and depth is 4m. step by step . time kam hai ​

Answer 1

Answer:

ANSWER

The dimension of the cistern are

Length =8m

Breadth =6m

Height =2.5m

We know that

Capacity of cistern= Volume of the cistern

Volume of cistern =1×b×h

By substituting the values

Volume of the cistern =8×6×2.5

By multiplication

Volume of the cistern =120 cm

3

We know that area of iron sheer required is equal to the total surface area of the cistern

So we get

Total surface area =2(lb+bh+lh)

Length =25 cm

By substituting the values

Total surface area =2(8×6+6×2.5+2.5×8)

On further calculation

Total surface area =2(48+15+20)

So we get

Total surface area =2×83=166 m

2

Therefore, the capacity of the cistern is 120 m

3

and the area of the iron sheet required to make the cistern is 166m
