Hey there!
To find the volume, we simply find the separate volumes of all three cubes and add them. The formula for volume in a cube is s^3 with s being one side. Therefore since all the sides are 6, the volume of one cube is 216 units cubed.
Now, we multiply that by three to get the total volume of the three cubes, to get 648 cubic units- so A.
Hope this helps!
Answer: Option A
Explanation: The lights that is incident on a mirror will be reflected back as it is a smooth surface and it reflects back the light.
the light will be reflected by the same angle as it was incidented. The angle of incidence can be defined as the angle by which the light ray falls on the surface of the mirror.
The angle by which the light reflects back is known as the angle of reflection. Being a smooth surface light ray is reflected back.
