Agift box is a rectangular prism14inches long,5inches wide, and 4inches high. if the box is to be covered in fabric ,how much fabric is needed if there is no overlap?

That's the surface area

when he length=L
width=W
and height=H

SA=2(LW+WH+LH)
so
L=14
W=5
H=4

subsitute
SA=2((14)(5)+(5)(4)+(14)(4))
SA=2(70+20+56)
SA=2(146)
SA=292

you need 292 square inches of fabric

B.the point lies directly on the regression
