Expressions 8-7

Determine if the problem is asking to find the volume, area, or length

Length tells how wide, tall, or long something is. Finding length requires one measurement. Length is one-dimensional and is measured in linear units.

Area tells how much surface a figure covers. Finding the area of a rectangle requires two linear measurements. Area is two-dimensional and is measured in square units.

Volume tells how much space an object occupies. Finding the volume of a rectangular prism requires three linear measurements. Volume is three-dimensional and is measured in cubic units.

To answer the question, tell if you need to measure for length, area, or volume. Then we will tell how the number of measurements you need to make.
