GED Mathematical Reasoning TestQuantitative Problem Solving with MeasurementEasy
A packaging company is designing a box in the shape of a rectangular prism. The box needs to hold a product that measures 5 inches long, 3 inches wide, and 2 inches high. What is the volume of the box required to fit this product exactly?
- A15 cubic inches
- B10 cubic inches
- C30 cubic inches
- D60 cubic inches
Show answer & explanationAnswer & explanation
Correct answer: C. 30 cubic inches
To find the volume of a rectangular prism, multiply its length, width, and height. In this case, 5 inches * 3 inches * 2 inches = 30 cubic inches.
Why the other options are wrong
- A. This would be the result of multiplying only two of the dimensions (e.g., 5*3).
- B. This would be the result of adding the dimensions instead of multiplying.
- D. This would be the result of a calculation error or multiplying by an extra factor.
Volume of a Rectangular Prism
The volume of a rectangular prism is the amount of space it occupies, calculated by multiplying its length, width, and height.
- Measured in cubic units (e.g., cubic inches, cm³).
- Formula: V = L × W × H
- Represents the capacity of a 3D object.
