What does origin mean
Artemon [7]

Answer: (0,0) on a coordinate plane

Step-by-step explanation:

The word origin has many definitions, but I see that you put this topic question under mathematics, So you are talking about an origin on a coordinate plane.

Origin means start or beginning, on a coordinate plane (Consisting of two lines, one vertical, the y-axis and one being horizontal, which is the x-axis), you would find the Origin in the middle of the place that the x-axis and the y-axis intersect

In the area where those axis's intersect is known as the origin and is also known as the points (0,0)

What is the surface area of the figure?
oksano4ka [1.4K]
We have 8 sides to calculate, it will be hard to explain which side I'm calculating without marking on the picture. 

We will start with the front facing side. We can break this up into an 8ft x 8ft square, and a 14ft x 6ft rectangle. The area equals: 
8ft x 8ft + 14ft x 6ft = 148ft^2

The front facing is the same area as is back facing counterpart so we can multiply the surface area by 2:
148ft^2 x 2 = 296f^2

Adding the bottom surface area 6ft x 14ft:
6ft x 14ft + 296ft^2 = 380ft^2

Adding the right side 6ft x 14ft:
6ft x 14ft + 380ft^2 = 464ft^2

Adding the left side 8ft x 6ft:
8ft x 6ft + 464ft^2 = 512ft^2

Adding the 3 sides on the top 8ft x 6ft (top facing), 6ft x 6ft (top facing), and 6ft x 6ft (left facing):
<span>8ft x 6ft + 512ft^2 = 560ft^2
</span><span>6ft x 6ft + 560ft^2 = 596ft^2
</span>6ft x 6ft + <span>596</span>ft^2 = 632ft^2

Therefore the answer is C, 632 ft^2.
