The area of the two triangular bases is
  A = (4 mm)(6 mm) = 24 mm²

The perimeter of the triangular base is
  P = 2(6.3 mm) + 4 mm = 16.6 mm
so the lateral area is
  A = (16.6 mm)(8 mm) = 132.8 mm²

The total surface area is the sum of the base areas and the lateral area.
  total area = 24 mm² + 132.8 mm² = 156.8 mm²

This value corresponds to selection ...
  D) 156.8 mm²

Give one combination of two factors whose product is 0.24, if one of the factors is a whole number greater than 1.
vitfil [10]

Answer: There are a lot of answers to this product. Some of them include (in the format (w, x), where w is the whole number, and x is the factor you must multiply it by to get 0.24):

(2, 0.12), (3, 0.08), (4, 0.06), (6, 0.04), and so on.


Step-by-step explanation: Well, you could just assign the smallest who number greater than 1 to one of the factors, which is 2. Now you just have to multiply that by another factor to get 0.24. To do this, you could set up an equation like this:

2*x=0.24

Next, you would divide both sides by 2 to cancel out the 2 on the left side of the equation, leaving you with:

x=0.12

There you have it!

Now you can check your work by multiplying 2 and 0.12, and you will get 0.24!

You can do the same thing with other whole numbers, such as 3 and 4, and complete the same process to find the decimal factor that multiplies to 0.24.
