Bellwork, Tuesday April 2, 2019 Turn to the next page in your Notebook. Add: Volume of Cubes and Rectangular Prisms

Volume of Cubes & Rectangular Prisms Volume is the amount a 3D container will hold. You measure volume in cubic units. How many cubic cm are in this rectangular prism? Answer: 12 cm³

5 5 5 125 ft³ 30 6 8 1,440 ft³

In Chapter 9, you solved equations with squares, such as x2 = 16, by using the square-root operation, √ . To solve equations with cubes, such as x3 = 64, you need an operation that undoes cubing. You need the operation called cube root. It uses the symbol ∛ .

Find the cube-root key on your calculator.  Different calculators perform this operation in different ways, so figure out how to do this on your calculator and then find 3 64   to get the solution to x3 = 64.
