- 10 meters3
- 20 meters3
- 16.875 meters3
- 17 meters3
Hint:
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: 16.875 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 2.5 meters, width is 4.5 meters, and height is 1.5 meters.
>>>The volume of any structure = (Are of base)
(Height)
>>>Then, the volume of a prism = (Area of a rectangular base)(Height)
= (Length width)(height)
= (2.5)(4.5)(1.4) meter3.
= 16.875 meters3.
>>>Therefore, the volume of a prism is 16.875 cubic meters.
Volume = 2.5×4.5×1.5
= 16.875 meters3.
