Question

A rectangular lap pool measures 100 feet long by 30 feet wide and 5 feet deep. Calculate its volume.

  1. 10000 feet3
  2. 12000 feet3
  3. 15000 feet3
  4. 15300 feet3

hintHint:

when it comes to mensuration one can find attributes of an structure in any method. Anyhow, once one has got an expression for volume of a structure then, substitute the values given and find the values needed.

The correct answer is: 15000 feet3


    In geometry, a rectangular prism is a polyhedron with two congruent and parallel bases. It is also called a cuboid. A rectangular prism has six faces, and all the faces are in a rectangle shape and have twelve edges. Because of its cross-section along the length, it is said to be a prism.
    Given That:
    A rectangular lap pool measures 100 feet long by 30 feet wide and 5 feet deep. Calculate its volume.
    >>>The Volume of any structure = (Area of the base)cross times(Height)
    >>>The Volume of the Prism = (Area of the rectangular Base)cross times(Height)
                                                   = (Length)cross times(Width)cross times(Height)
    = (100)cross times(30)cross times(5)
    = 15000 feet3.
    >>>Therefore, the volume of the prism is 15000 cubic feet. 

    Volume = 100×30×5
    15000 feet3.
