The volume of the rectangular prism is 1/10 cubic units
<h3>Volume of a rectangular prism</h3>The formula for calculating the volume of a rectangular prism is expressed as;
V = Bh
B is the base area
h is the height
Given the following parameters
B = 3/20 units²
h = 2/3 units
Substitute
V = 3/20 * 2/3
V = 2/20
V = 1/10 cubic units
Hence the volume of the rectangular prism is V = 1/10 cubic units

Answer:
Age of son = 6 years
Age of man = 5×6 = 30 years
Step-by-step explanation:
<u>GIVEN :-</u>
- A man is 5 times as old as his son. (In Present)
- 4 years ago , the man was 13 times as old as his son
<u>TO FIND :-</u>
- The present ages of the man & his son.
<u>SOLUTION :-</u>
Let the present age of son be 'x'.
⇒ Present age of man = 5x
4 years ago ,
Age of son = (Present age of son) - 4 = x - 4
Age of man = (Present age of man) - 4 = 5x - 4
The man was thirteen times as old as his son. So,
Now , solve the equation.
- Open the brackets in R.H.S.
- Take 5x to R.H.S. and -52 to L.H.S. Also , take care of their signs because they are getting displaced from L.H.S. to R.H.S. or vice-versa.
- Divide both the sides by 8
<u>CONCLUSION :-</u>
Age of son = 6 years
Age of man = 5×6 = 30 years
