A storage tank is in the form of a cube. when it is full of water, the volume of water is 15.625m³ .if the present depth of water is 1.3 m,find the volume of water already used from tank
Answers
Answer:
Let side of a cube be = x m
∴ Volume of cubical tank = 15.625 m3 [given]
⇒ x3 = 15.625 m3
⇒ x = 2.5 m
and present depth of water in cubical tank = 1.3 m
∴ Height of water used =2.5 – 1.3 m = 1.2 m
Now, volume of water used = 1.2 x 2.5 x 2.5= 7.5 m3
= 7. 5 x 1000 = 7500 L [∴ 1 m3 = 1000 L]
Hence, the volume of water already used from the tank is 7500 L.

HEY MATE HERE IS YOUR ANSWER
Let side of a cube be = x m∴ Volume of cubical tank = 15.625 m3 [given]⇒ x3 = 15.625 m3⇒ x = 2.5 mand present depth of water in cubical tank = 1.3 m∴ Height of water used =2.5 – 1.3 m = 1.2 mNow, volume of water used = 1.2 x 2.5 x 2.5= 7.5 m3= 7. 5 x 1000 = 7500 L [∴ 1 m3 = 1000 L]Hence, the volume of water already used from the tank is 7500 L.
