Answer:
Density = 0.4g/cm³
Explanation:
Given
Mass = 12 g
Length = 3 cm
Required
Determine the density.
To calculate density, we need volume.
Volume of a cube is:
Volume = Length ³
Hence:
Volume = (3cm)³
Volume = 27cm³
Density = Mass/Volume
Density = 12/27
Density = 0.4g/cm³ --- Approximated

- Bicycling on the road - voluntary action
- Beating of the heart - involuntary but non-reflexive action
- Jumping when startled by a loud horn - reflexive action
- Blinking your eyes every few seconds - reflexive action controlled by the brain
Reflexive actions are the simple and fundamental movements. Those are automatic muscle responses to particular stimuli. Examples: removing the arm when it burns, moving the feet when it step tt a sharp object etc.
Voluntary actions are under the control of the brain which “orders” and sends information to motor cortex to perform the movement. Examples: arm and leg moving, doing any sport etc.
Involuntary actions are made without the intermediation of the brain. Examples: crying, blinking, breathing, heart beating etc.
