In this Grade 6 enVision Mathematics lesson, students learn how to calculate the volume of rectangular prisms with fractional and decimal edge lengths by applying the volume formula V = l × w × h. The lesson covers multiplying mixed numbers and decimals to find volume, as well as working backwards from a known volume to find a missing dimension. These skills are practiced through real-world problems involving objects like gift boxes, school lockers, and shipping boxes.
Section 1
Volume
We use cubic units to measure the volume or amount of space inside a three-dimensional object. For a box with dimensions length , width , and height , the volume is found by multiplying the three dimensions.
Section 2
Volume of a Cube
A cube is a rectangular prism whose length, width, and height are all equal. For any cube with sides of length :
Volume:
