A rectangular piece of metal is 25 inches longer than it is wide. Squares with sides longer than it is wide.Squares with sides 5 inches long are cut from the four corners and the flaps are folded upward to for an open box. If the volume of the box is 750 in^3, what were the original dimensions of the piece of metal?
What is the original width?
Answer provided by our tutors
x(x+25)*5= 750
x(x+25)= 150
so, x= 5 and x+25= 30
so,
original dimension was: 5+2*5= 15in
and 30+2*5= 40in
so, original dimensions was: length= 40 in and width= 15 in.
