Cary calculated the surface area of a box in the shape of a rectangular prism. She wrote the equation 148=2(6w+6h+hw) to represent the width and height of the box. She solved for w and got w=74-6h/h+6 Which of the following is an equivalent equation?
1.w=148-6h/12+h
2.w=148-12h/12+2h
3.w=136-14h
4.w=136-10h
1.w=148-6h/12+h
2.w=148-12h/12+2h
3.w=136-14h
4.w=136-10h
