First, let's make a possible dimension of the prism.
We have to divide 60 by a number so when you multiply those three numbers it equals 60. We can try multiplying 5 by 4 by 3 and it gets us 60. This is one possibility.
So now we triple the sides.
Triple is to make three times as much (multiply by three)
5*3=15
3*3=9
4*3=12
Now lets find the volume
Volume= l*w*h
Volume= 15*9*12=1,620
I think this would work for any dimension you choose.
The volume of the prism will be 1,620 in3 if the dimensions were tripled.
(Sorry, this took me long time to type.)
