23 cm
Alenkasestr [34]

Answer:

445.2 square cm

Step-by-step explanation:

The surface area consists of  area of two bases and area of three leteral faces. Each lateral face is a rectangle with length of 23 cm and width of 6 cm.

The area of rectangle is

A_{rectangle}=\text{length}\times\text{width}

So,

A_{rectangle}=23\times 6=138\ cm^2

The area of base is given as 15.6\ cm^2

Thus, the surface area is

SA=2A_{base}+3A_{lateral\ face}\\ \\SA=2\cdot 15.6+3\cdot 138=445.2\ cm^2

15 POINTS !!!!
Natalija [7]
So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out. 

So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

I hope this helps you! If it does, please rate as Brainliest :D
