Given:
Brandon has a box 9.5 inches tall, 3.8 inches wide, and 4.2 inches long.
Determine the area.
Formula for the area of the box:
A=2lw+2lh+2hw
Solution:
Substitute the given values to the formula for the area of the box.
A=2lw+2lh+2hw
A=2(4.2 in)(3.8 in)+2(4.2 in)(9.5 in)+2(9.5 in)(3.8 in)
A= 31.92 in^2+ 79.8 in^2 + 72.2 in^2
A = 183.92 in^2
Final answer:
183.92 in^2 of wrapping paper is needed to wrap the box.
