If a = 7, b = 6, c = 8, and d = 7, what is the perimeter of this quadrilateral?

88% Answer Correctly
16
29
15
28
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 7 + 6 + 8 + 7
p = 28

The dimensions of this cube are height (h) = 2, length (l) = 2, and width (w) = 4. What is the surface area?

51% Answer Correctly
88

40
22
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 4) + (2 x 4 x 2) + (2 x 2 x 2)
sa = (16) + (16) + (8)
sa = 40
