Question

23.
A rectangular water reservoir contains 72000 litres of water. Find the depth of water in the reservoir,
its base measures 8 m by 4.5 m.​

Answer 1

Answer:

Volume of rectangle is length x breadth x height (depth)

8 x 4.5 x depth = 72 ( as for converting in litres it is multiplied by 1000)

36 x depth= 72

depth = 72/36

Therefore depth = 2 m

Answer 2

Answer:

Volume of rectangle is length × breadth × height {depth}

8 × 4.5 × depth = 72 (as for converting in litres is multiply by 1000)

36× depth = 72

depth = 72/36

there for depth = 2m
