Volume Calculations
Volume is the amount of 3-dimensional space inside a shape. If the shape is a prism we can use the area of the end to calculate the volume. We can use the following formula: The volume of a prism = Area of base × height A prism is a 3-dimensional...
Calculating Perimeter, Area, and Volume
Perimeter Calculations Perimeter is the length around the outside of a figure. Normally we only look at 2-dimensional figures; however, the concept of total length can also apply to 3-dimensional figures which have a framework as well as any covering which will be...
Measuring Lengths and Distances
In the next section, formal methods are used for calculating perimeter, area and volume; however, it is always important to have a method for checking how sensible an answer is. The following two sub-sections outline methods for estimating lengths, distances, area and...
