KEY MATH LEARNING
1. The formula for the volume of a rectangular prism is the area of its base multiplied by its height. V = (area of base) x h OR v = ah
2. The shape of the prism does not effect its volume calculation.
VOCABULARY
volume - the amount of space occupied by an object
capacity - the amount a container can hold.
HOMEWORK
Q: What would the area of the base represent if you filled the box with 1cm cubes?
A: It would represent the area of the bottom layer of the box.
Q: If you filled your box with 1cm cubes, what would the height represent?
A: The number of layers of 1cm cubes the box can hold.
Q: What are the variables for the volumes of a box?
A: The dimensions.
Q: Will the volume of the box be different if it sits on a different face?
A: The volume will NOT change because its size and dimensions will remain the same.

face - any of the polygons that make up and object's boundaries.
prism - an object that has two congruent and parallel faces (bases) and other faces that are parallelograms.
edge - where, on the shape, two or three sides meet.
perpendicular - at a 90 degree angle.
polygon - a closed shape consisting of line segments.
vertex - the point where two sides on a shape meet, or the point where three or more edges meet.
right prism - A three-dimensional shape with two identical parallel bases, with all other faces as rectangles.
regular polygon - a polygon having all sides and angles equal.
congruent - shapes that match exactly but don't always have the same orientation.

Math Makes Sense 8 - Chapter 4: Measuring Prisms and Cylinders VOCABULARY
net - a pattern that can be folded to make an object.
polygon - a closed shape that consists of line segments (ex. triangles and quadrilaterals are polygons).
polyhedron - an object with faces that are polygons.
quadrilateral - a four-sided polygon.
