Answer 1

what does 4 * 12 mean what does the * mean

Answer 2

The formula for the surface area of a square pyramid is given by:

Surface area = base area + (0.5 * perimeter of base * slant height)

First, calculate the base area:
Base area = (12)^2 = 144

Next, calculate the perimeter of the base:
Perimeter of base = 4 * 12 = 48

Now, substitute these values into the formula:
Surface area = 144 + (0.5 * 48 * 18)
Surface area = 144 + 432
Surface area = 576

Therefore, the surface area of the square pyramid is 576.

Answer 3

In mathematics, the symbol "*" represents multiplication. When we calculate the perimeter of a square, we multiply the length of one side by 4 to get the total distance around the square, which is the perimeter.

So, 4 * 12 means multiplying 4 by 12, which equals 48 in this case.
