guys 1.32 is the total profit which includes profit to the company and commision to the employee. So after subtracting the commission from the total profit we will get the profit earn by the company itself

Read question carefully , "Later on it found that the box capacity is 20% less means the current box is 20% less we need 20% more space.
in the cuboidal question please elaborate it sir
in the cuboidal box example why did you divided the old capacity by 0.8...i didn't understand that?
cuboidal questions new capacity = 16*12*5/0.8 how is it ?
