Answer:
Cube with a side length of 2/5 cm: 8/125 cm^3
Rectangular prism with a length, width, and height of 3/5 cm, 4/5 cm, and 3/5 cm, respectively: 36/125cm^3
Rectangular prism with a length, width, and height of 1/5 cm, 2/5 cm, and 3/5 cm, respectively: 6/125 cm^3.
Cube with a side length of 1/5 cm: 1/125 cm^3
Step-by-step explanation:
For the first one, cubes have equal sides, we would do 2/5*2/5*2/5, which is 8/125 cm^3.
Next we have a rectangular prism. For this, we will just multiply all of the sides with each other which is 3/5*4/5*3/5 which is 36/125 cm^3
Now we have another rectangular prism. Again, we will multiple all of the sides with one another: 1/5*2/5*3/5, which is 6/125 cm^3.
Lastly, there is a cube with a side length of 1/5 cm. We know that cubes have equal sides, so it would be 1/5*1/5*1/5, which is 1/125 cm^3.
I hope this helped.
