Answer:
68 m^2
Explanation:
There are two faces that are parallelograms. Each of those has an area that is the product of length and width:
(2 m)·(4 m) = 8 m^2
There are two faces that are rectangles. Each of those has an area that is the product of length and width:
(2.5 m)·(4 m) = 10 m^2
There are two faces that are square. Each of those has an area that is the square of the edge length:
(4 m)^2 = 16 m^2
The surface area is the sum of the areas of the pairs of faces:
surface area = 2(8 m^2 + 10 m^2 + 16 m^2) = 2·34 m^2
surface area = 68 m^2
