Grade 5 · Math · Volume and Measurement · Connecticut, USA
Lesson Summary
Use the formula length x width x height to find the volume of a rectangular prism.
Explanation
For a rectangular prism (a box shape), you can find the volume by multiplying length times width times height. This works because you are finding how many unit cubes fit along each edge. For example, a box that is 4 cm long, 3 cm wide, and 2 cm tall has a volume of 4 x 3 x 2 = 24 cubic centimeters. Make sure all three measurements use the same unit before you multiply.

Q2: A rectangular prism has a length of 10 cm, a width of 2 cm, and a height of 6 cm. What is its volume?
