Explore volume as an attribute of three-dimensional figures by packing them with unit cubes without gaps. Find the volume of a right rectangular prism with whole-number side lengths by counting unit cubes.

Find the volume of a right rectangular prism with whole-number side lengths using a visual model and a formula.

Solve real-world problems involving the volume of right rectangular prisms, including problems with an unknown edge length, with whole-number edge lengths using a visual model or a formula. Write an equation with a variable for the unknown to represent the problem.

Volume is the amount of space that an object takes up.

It can help to think of volume as the number of unit cubes that can fit inside an object.

In this 3-inch cube, think of how many 1-inch cubes would fit on the bottom layer of the cube.
