If you have a cube with a length of 1 1/3inches, width of 1 inch, and height of 2/3 inch and you find the volume of the right rectangular prism using the formula method and want to check your answer using the cube method. What is the edge length of the cubes you will use
To find the volume of the right rectangular prism using the formula method, you can use the formula V = l x w x h, where l is the length, w is the width, and h is the height.
Plugging in the values, we get V = (1 1/3) x 1 x 2/3 = 4/3 x 1 x 2/3 = 8/9 cubic inches.
To check this answer using the cube method, you can divide the volume of the right rectangular prism by the volume of a cube to find the number of cubes. Since the volume of a cube is equal to the edge length cubed (V = e^3), you can rearrange the formula to solve for the edge length: e = V^(1/3).
Plugging in the volume of the right rectangular prism, we get e = (8/9)^(1/3) = (2/3) inches.
Therefore, the edge length of the cubes you will use is 2/3 inches.
