Answer:
78mm^2
Step-by-step explanation:
based on the information given, we can tell that the shape of the MP3 player is a rectangle. The formula for the surface area of a rectangle is SA=2WL+2LH+2HW
SA = Surface Area
W = Width
L = Length
H = Height
SA = 2(4)(7) + 2(7)(1) + 2(1)(4)
= 2(28) + 2(7) + 2(4)
= 56 + 14 + 8
= 78
I believe the answer is 5.73
