Final answer:
To find the volume of the matchstick, you need to multiply its length, width, and height. Convert the measurements to the same unit, such as meters, and then use the formula volume = length x width x height.
Step-by-step explanation:
To find the volume of the matchstick, we need to multiply its length, width, and height. However, we need to make sure that all the measurements are in the same unit. Let's convert all the measurements to meters first.
Length = 0.04 m
Width = 3 cm = 0.03 m
Height = 10 mm = 0.01 m
Now, we can calculate the volume using the formula: Volume = Length x Width x Height
Volume = 0.04 m x 0.03 m x 0.01 m = 0.000012 m³
The volume of the matchstick is 0.000012 cubic meters.
