Final answer:
The surface area of the rectangle is 160 square units.
Step-by-step explanation:
The surface area of a rectangle can be found by adding up all of its side areas. Since the rectangle has a height of 8, a width of 4, and a length of 4, you can find the total surface area by calculating:
Surface Area = 2(Length x Width) + 2(Length x Height) + 2(Width x Height)
Substituting the given values, we get:
Surface Area = 2(4 x 4) + 2(4 x 8) + 2(4 x 8)
Simplifying this equation gives us:
Surface Area = 32 + 64 + 64 = 160 square units
