Find the volume of a right rectangular prism with whole-number side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold whole-number products as volumes, e.g., to represent the associative property of multiplication.

An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.

Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.

Apply the formulas 𝘝 = 𝘭 × 𝘸 × 𝘩 and 𝘝 = 𝘣 × 𝘩 for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real world and mathematical problems.

Geometric measurement: understand concepts of volume and relate volume to multiplication and to addition.

A square with side length 1 unit, called “a unit square,” is said to have “one square unit” of area, and can be used to measure area.

Understand area as an attribute of plane figures and understand concepts of area measurement, such as square units without gaps or overlaps.
