Let x represent the weight of a large box, and y represent the weight of a small box. The problem statement gives rise to two equations in these unknowns:
.. 12x +2y = 253
.. 3x +5y = 133
A graph shows these equations have solution
.. x = 18.5
.. y = 15.5
A large box weighs 18.5 kg.
A small box weighs 15.5 kg.
The volume of a cube with side length equal to x, is
,
thus, the volume of a cube shaped box, whose side length is (5a+4b) is :
,
The volume is already expressed in terms of a and b, but we can expand the expression
, as follows:
