Question

A Cuboidal vessel is 10 m long and 8 m wide. How high must it be made to hold 380 cubic meters of a liquid ?

hintHint:

  • A cuboid is a solid 3 dimensional figure with six-faces, 8 vertices and 12 edges. Its faces are rectangles.
  • Volume is the capacity of a certain object to carry or hold another objects within i.e. the amount of space that the object holds. Volume of a cuboid = length cross times width cross times height

The correct answer is: The given cuboidal vessel must be 4.75 m high to hold 380 m3 of liquid.


    Step-by-step solution:
    From the given information, we get-
    • Length = 10m
    • Width = 8m
    • Height = ?
    • Volume = 380 m3
    Now, we know that, Volume of a cuboid = length cross times width cross times height
    ∴ Volume of the given cuboidal vessel = length cross times width cross times height
    ∴ 380 = 10 cross timescross times Height ................................... (From given information)
    ∴ 380 = 80 cross times Height ........................................ (Equation i)
    ∴ 380 / 80 = Height ............................................... (Dividing both sides by 80)
    ∴ 4.75 m = Height
    ∴ The given cuboidal vessel must be 4.75 m high to hold 380 m3 of liquid.
