Asandwich shop uses the box size shown to pack boxed lunches. they have determined that they need to use bigger boxes. if the side lengths of the square faces are changed to 7 inches, by how much will this increase the volume of the box?

240 cubic cm

Step-by-step explanation:

Volume of the box before increament in sides = length*width*height

Length= 5 in.

Width=5 in.

Height = 10 in.

Putting these vales in formula

Volume of box = 5*5*10

                        =

Now  If the side lengths of the square faces are changed to 7 inches,

So, Length will be 7 in.

Width will be 7 in.

So, new volume = 7*7*10

                          =

Thus increase in volume = 490-250 =240

Hence by 240 cubic cm  will this increase the volume of the box
