Solution

The area of a parallelogram is equal to its length x width:

a = l x w
a = a x b
a = 3 x 9
a = 27

The dimensions of this cube are height (h) = 1, length (l) = 2, and width (w) = 9. What is the surface area?

51% Answer Correctly
58
78
62
138
Solution

The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):

sa = 2lw + 2wh + 2lh
sa = (2 x 2 x 9) + (2 x 9 x 1) + (2 x 2 x 1)
sa = (36) + (18) + (4)
sa = 58
