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

Answer 1

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.
