Abox has a length of 2x+2 and the width of x-2 has a primiter of 90 cm. if the hight of the box is x what is the volume of the box a)416 cm^3 b)480 cm^3 c)3375 cm^3 d)5358 cm^3 e)6240 cm^3update it is e) 6240cm^3  

We know that
volume of the box=length*width*height

length=2x+2
width=x-2
height=x

perimeter of the box=2*[length+width]
90=2*[2x+2+x-2]> 90=2*3x> 6x=90> x=15 cm
so
length=2x+2> 2*15+2> 32 cm
width=x-2> 15-2> 13 cm
height=x> 15 cm

volume of the box=32*13*15> 6240 cm³

the answer is
6240 cm³
