rectangular prism is made up of four cubes that are 1/5 in on each side use the cube method or the formula method to find the volume reduce your answer to lowest terms
To find the volume of the rectangular prism made up of four cubes, we can use either the cube method or the formula method.
Cube Method: Since each cube has sides of 1/5 inch, the volume of each cube is (1/5)^3 = 1/125 cubic inches. Since there are four cubes in the rectangular prism, the total volume is 4 * 1/125 = 4/125 cubic inches.
Formula Method: The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height. Since each cube has sides of 1/5 inch, the length, width, and height of the rectangular prism are all 1/5 inch. Plugging these values into the formula, we get V = (1/5)(1/5)(1/5) = 1/125 cubic inches.
Therefore, the volume of the rectangular prism made up of four cubes is 4/125 cubic inches.
