Margaret is wrapping a box. The box is a rectangular prism that is 18 inches long, 12 inches wide and 9 inches tall. How much wrapping paper will she need? Group of answer choices

i think she would need about 78 inches of wapping paper

Step-by-step explanation:

She will need 3 more inches of wrapping paper to wrap the box.

Step-by-step explanation:

add 12 and 9 the subtract the answer by 18

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
