Bryan is wrapping a birthday gift in the rectangular box
shown below. He wants to cut just one rectangular piece
of wrapping paper to cover the box.
7 in
13 in and 4in
What is the area of the smallest piece of paper that Bryan
can use the wrap the gift?

Given:

Dimension of box is 7 in, 13 in and 4 in.

To find:

Area of the smallest piece of paper

Solution:

Area of the rectangular box = length × width × height

                                               = 7 × 13 × 4

Area of the rectangular box = 364 in³

Area of the rectangular box = Area of the gift paper to wrap the box

Therefore the area of the smallest piece of paper is 364 in³.

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
