Front = 56cm2
Back = 56 cm2
Top and Bottom
Bottom = 40cm2
Left = 5 x 7 = 35
Right = 5 x 7 = 35
56 + 56 + 40 + 40 + 35 + 35 =
112 + 80 + 70
Height = 5cm

Whats the difference between
surface area and volume?
Surface Area= How much skin is
covering an object
Outside of the box
Example: How much cardboard is
needed to make this box?
Volume = How much space is
inside an object
Inside the Box
Area is the amount of space a 2-D
object takes up
3-D: Surface Area
Surface Area is how much space
there is on every side of a 3object.
