Multiply length × width × height, in any order. For a shape made of two boxes, find each box's volume, then add them.
volumethe space inside a solid, in cubic units
length, width, heightthe three edges of a box
V = l × w × hvolume = length × width × height
basethe bottom face: its area is l × w
Watch for: Adding the three measurements instead of multiplying them. Multiplying only two of the three measurements. Multiplying the two boxes' volumes together instead of adding them.
At home: Measure a cereal box or shoebox to the nearest inch and find its volume. Which box in the kitchen holds the most?
