Question

4. A 20 m long and 10 m wide rectangular
tank contains water upto the depth of 2 m.
The water was transferred to another
rectangular tank measuring 10 m long and
5 m wide. In the new tank the water will
measure upto a depth of
(1) 8 m
(2) 6 m
(3) 4 m
(4) 2 m​

Answer 1

Answer:

8 m

Step-by-step explanation:

given that volume of the tank will be equal for

they contain same amount of water

so ,

let the depth of second tank be y then,

20×10×2=10×5×y

20×10×2/10×5=y

8 = y

Hence, the depth of second tank will be 8m

Answer 2

Answer:

(3)4m

Step-by-step explanation:

Given = tank 1=L=20m

=b=10m

Water depth=2m

Tank2=L=10m

=b=5m

.

Area of tank 1=20*10=200sq m

Area of tank 2=10*5=50 sq m

Water depth in tank 2=200/50

=4m
