Step-by-step explanation:
The volume of a rectangular parallelepiped is given as 144 cc. Its surface area is given as 192 sq cm. And its corner to corner diagonal is given as 13 cm. How do I find out the three sides.
I have assumed the sides to be a,b,c. Now, a2+b2+c2=169,2(ab+bc+ca)=192, and abc=144. How do I solve the three equations without forming a cubic equation? (This is a class 9 problem so i am not suppoesd to use solution to cubic equations.)
