Question

Water in a canal 1.5m wide and 6m deep is flowering with a speed of 10km/ hr. how much area

Answer 1

Answer:volume of canal = l×b×h

So b=1.5m and h =6 m

Again length (d)= s×t

=10×1

=10 km

=1000m

Therefore,

Volume of canal = 9000m

LxBxH = 9000m

LxB=9000/H

=1500m.square

Step-by-step explanation:

Answer 2

ANSWER

Canal is in the shape of cuboid , where,

Breadth =6 m

Height =1.5 m

Speed of canal =10 km/hr

Length of canal in 1 hour =10 km

Length of canal in 60 minutes =10 km

Length of canal in 1 minute = 1/60×10km

Length of canal in 30 minute =30/60×10=5000 m

Now,

Volume of canal = length×breadth×height

= 5000×6×1.5 m^3

Now,

Volume of water in canal = Volume of area irrigated

Volume of water in canal = Area irrigated × Height

5000×6×1.5 = Area irrigated × 8/100

Area irrigated = 56.25 hectares
