Question

A water tank is 1.2 m square and 1.35 m deep. It is half full of water.How many times

Answer 1

Answer:

Well, the tank's volume is 1.2 x 1.2 x 1.35 = 1.944 m³ = 1944 litres.

It is half-full, so it contains 1944 / 2 = 972 litres of water.

That is enough to fill 972 / 9 = 108 9-litre buckets.

Step-by-step explanation: h = height of water = 1.35 m/2 = 0.675 m    

A = area of tank = s² = (1.2 m) = 1.44 m²    

V = volume of water    

V = Ah = (1.44 m²)(0.675 m)
