Question

Find the volume of the rectangular prism whose length is 9 meters, width is 12 meters, and height is 7 meters.

  1. 730 meters3
  2. 700 meters3
  3. 756 meters3
  4. 800 meters3

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: 756 meters3


    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:
    The volume of the rectangular prism whose length is 9 meters, width is 12 meters, and height is 7 meters.
    >>>Volume of any structure = (Area of the Base)cross times(Height)
    >>>Volume of the Prism = (Area of the rectangular Base)cross times(Height)
                                            = (Length)cross times(Width)cross times(Height)
    = (9)cross times(12)cross times(7)
    = 756 meters3.
    >>> Therefore, the volume of the prism is 756 cubic meters.

    Volume = 9×12×7
    756 meters3.
