4a. 99m + 81 = 130m. 4b. 40 + 30z = 70z
5a. 24v + 18 = 41v. 5b. 12c + 16 = 28c
6c. 44 + 48v= 92v. 6b. 40 + 12s = 52s.

Answer:
Volume =  cubic centimeter
 cubic centimeter
Step-by-step explanation:
Let the length of each side of the base of the box  be A and the height of the box be H. 
Area of material required to make the box  is equal to  is 
 
  Rearranging the above equation, we get -  

Volume of box is equal to product of base area of box and the height of the box -  

Substituting the given area we get - 

For maximum volume 



Volume of the box 
= 
=  cubic centimeter
