If 1 inch = 2.54 cm Determine the relationship between cubic inches and cubic centimeters? Show your work in this space.
The Correct Answer and Explanation is:
To determine the relationship between cubic inches and cubic centimeters, we start with the given:
1 inch = 2.54 centimeters
We want to find how many cubic centimeters are in 1 cubic inch.
Step-by-step conversion:
A cubic inch means:1 in3=1 in×1 in×1 in1 \text{ in}^3 = 1 \text{ in} \times 1 \text{ in} \times 1 \text{ in}1 in3=1 in×1 in×1 in
Since 1 inch = 2.54 cm, we can write:1 in3=(2.54 cm)×(2.54 cm)×(2.54 cm)1 \text{ in}^3 = (2.54 \text{ cm}) \times (2.54 \text{ cm}) \times (2.54 \text{ cm})1 in3=(2.54 cm)×(2.54 cm)×(2.54 cm)1 in3=2.543 cm31 \text{ in}^3 = 2.54^3 \text{ cm}^31 in3=2.543 cm31 in3=16.387064 cm31 \text{ in}^3 = 16.387064 \text{ cm}^31 in3=16.387064 cm3
So, the final relationship is:1 cubic inch=16.387064 cubic centimeters\boxed{1 \text{ cubic inch} = 16.387064 \text{ cubic centimeters}}1 cubic inch=16.387064 cubic centimeters
Explanation:
When converting between units of volume, it is essential to understand how linear measurements scale. The original conversion tells us that one inch equals 2.54 centimeters. However, when measuring volume, which involves three dimensions, each linear dimension is multiplied. Therefore, to convert from cubic inches to cubic centimeters, we must cube the conversion factor between inches and centimeters.
To see how this works, consider a cube with sides of 1 inch. The volume of this cube is calculated by multiplying the length by the width by the height, which is 1 inch × 1 inch × 1 inch or 1 cubic inch. Now, if we convert each inch to centimeters, each side becomes 2.54 centimeters. The volume of this new cube is then 2.54 × 2.54 × 2.54 cubic centimeters. Performing this calculation gives 16.387064 cubic centimeters.
This means that a single cubic inch contains approximately 16.39 cubic centimeters. This relationship is particularly useful in science, engineering, and manufacturing, where conversions between imperial and metric units are common. For example, if a machine part’s volume is given in cubic inches and you need to work in metric units, you multiply the volume in cubic inches by 16.387064 to get the volume in cubic centimeters.
This precise conversion is based on the standard definition of an inch as exactly 2.54 centimeters. Since the metric system is based on powers of ten, this conversion is reliable and can be used in any context requiring accurate volume measurements across unit systems.
