A Small Town has a population of 2000 A water tank of a dimestion 12x10x²16 m is to be const from above info Ams, the following 9 It the dimension of brick 10 X 45 X 20 How many bricks are required to cont this tant. ii's The tank is to be flaster from inside and outside at a rate €30m/5g Find the cost of blastering It a person require 12I of water perth ber to day for how many does the water of tank gast ins of cash person require yol of water bes day for how many day, will the water of the tank last​

Answer 1

Answer:

Length l=12m

Breadth b=9m

Height h=4m

⇒ Total surface of the tank =2(l×b+b×h+h×l)

=2(12×9+9×4+4×12)

=2×(108+36+48)

=192×2

=384m

2

⇒ Length of the sheet required = 2384

m =192m

∴ Cost of the sheet =192×5

=960

∴ Total cost of the sheet =Rs.960.

Hence, the answer is 960.

Answer 2

Answer:

Given:

⇒l×b×h=20×15×6

⇒Capacity of tank =l×b×h=(20×15×6)m^3

=1800m^3

=1800000 litre

⇒Consumption of water in 1 day =4000×150 litres

=600000 litres

⇒Water of this tank will last for = 1800000/600000

=3 days
