Question

a rectangular tank is 8m long, 6m wide, and 6m high.if it is filled with water up to the height of 4m, what is the volume of air left in the tank?

Answer 1

V = 8 * 6 * 4
what is value of V you get?

Answer 2

L X W X H= volume.

so 8 X 6 X 6 = total volume.

minus the water volume,
which is 8 X 4 X 6
and that's the air volume

Answer 3

@meme_90 did you get the answer?

Answer 4

@uzumakhi why did you use 4 for the height?

Answer 5

Because that's the water height... If you minus the water volume from the tank volume, you get the air volume

Answer 6

bcoz water is upto 4cm and you have to calculate the volume of water only

Answer 7

@order can you show the solution for it?

Answer 8

V = 192 cm^3

Answer 9

Ok:
L X W X H= volume

Volume of tank =

8 X 6 X 6 = value 1

Volume of water =

8 X 6 X 4 = value 2

Value 1 - value 2 = volume of air

Answer 10

calculate volume of air and then subtract from 192

Answer 11

The volume of water is 192 cm^3... not the air... so you still need to do what uzumakhi and I said to get the final answer. Understand?

Answer 12

yes @order

Answer 13

What will be the unit?

Answer 14

Unit? volume = m^3

Answer 15

The tank and water are in meters... and raising it to the power of 3 give you the volume unit. :)

Answer 16

so not, 192 cm^3, but 192 m^3

Answer 17

For the water in the tank ^^
