Answer:
160.0 cubic units
Rectangular prism with length 10, width 4, height 4 units
Identify the formula for volume of a rectangular prism
Substitute the dimensions
Multiply all dimensions
Final answer
V = length × width × height
This formula calculates the volume of a rectangular-prism.
A box measuring 10cm × 4cm × 4cm holds 160.0 cubic centimeters
A room 10m long, 4m wide, 4m tall = 160.0 cubic meters
The volume of a rectangular-prism is a fundamental concept in geometry that students encounter from elementary school through college-level mathematics. Volume measures the amount of three-dimensional space occupied by an object. It tells us the capacity of a container or how much space an object takes up. Volume is expressed in cubic units (like cubic meters, cubic feet, or liters) because we are measuring space in three dimensions.
By using the formula V = length × width × height, we can quickly and accurately calculate the volume for any rectangular-prism when we know the required measurements. This formula has been mathematically proven and is universally accepted in mathematics, engineering, architecture, and science.
A rectangular prism (also called a cuboid or rectangular box) is a three-dimensional shape with six rectangular faces. It's the 3D equivalent of a rectangle and is defined by three measurements: length, width, and height.
The volume formula (V = length × width × height) extends naturally from area: if we stack unit cubes inside the prism, we get length × width cubes on the base, and we stack them height times high.
Rectangular prisms are fundamental in packaging, shipping, architecture, and storage. Understanding their volume helps optimize space usage and calculate capacities.
Confusing volume with surface area
Volume measures the space inside (cubic units), while surface area measures the outer surfaces (square units).
Not using cubic units
Volume must always be in cubic units (m³, ft³, cm³). Remember: if measuring in meters, your answer is in cubic meters.
Mixing up radius and diameter
The radius is half the diameter. Using diameter when the formula requires radius will give you an answer 4x or 8x too large!
Sketching the shape with labeled measurements helps you visualize the problem and choose the right formula.
Make sure all measurements use the same units before calculating. Convert if necessary.
Before calculating, estimate what a reasonable answer might be. This helps catch major errors.
Writing out each step helps prevent errors and makes it easier to find mistakes if your answer seems wrong.

Ask: "Does this answer make sense?" A room can't have an area of 2 square meters if the sides are 10m each.
The formula is V = length × width × height. This formula allows you to calculate the volume when you know the required measurements: length, width, height.
Using the formula V = length × width × height, substitute your values: length=10, width=4, height=4. Following the calculation steps, you get 160.0 cubic units.
Volume is always measured in cubic units. If your measurements are in centimeters, volume will be in cubic centimeters (cm³). If in inches, you'll get cubic inches (in³).
Rectangular-prism volume calculations help with: determining container capacity, calculating water in pools or tanks, measuring shipping box sizes, and figuring out how much material fills a space.
When we apply the formula V = length × width × height with the values length=10, width=4, height=4, the mathematical operations give us exactly 160.0 cubic units. Each step in the solution follows mathematical rules that have been proven to always give correct results.
You must convert all measurements to the same unit before calculating. For example, if one measurement is in meters and another is in centimeters, convert one to match the other first. 1 meter = 100 centimeters, 1 foot = 12 inches, 1 yard = 3 feet.
