Question

1. A rectangular water reservoir contains 84,000 litres of water. Find the depth of the water in the reservoir if its base measures 6m× 3.5 m

Answer 1

Step-by-step explanation:

We know that volume of cuboid = length×breadth×height

So, height =Volume/lb

h=V/lb

h=42/(6×3.5)

h=2 m

Answer 2

Answer:

4m

Step-by-step explanation:

84,000litres = 84000/1000 = 84m³

Base area = 6*3.5 = 21m²

Depth = h

lb = 21m²

Equation :-

lbh = volume

21*h=84m³

h=84/21

h=4m

Another answer was given, and it is wrong, due to a wrong value, 42 is not given anywhere.

Thanks for the question.
