Arectangular jewelry box cost $125 to gold plate. calculate the cost of gold plating a box which is similar in shape and that holds 8 times as much

The cost of plating a rectangular jewelry box is $125, the cost of plating a similar box that is 8 times the size will be given by:
Cost=(scale factor)*(price)
Cost=125×8
Cost=$1000
$1000

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.

2+1=3 that’s your answer
