Answer:

169 $cm^2$

Step-by-step explanation:

The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.

(7) * (5) = (35)

(9) * (5) = (45)

(7) * (5) = (35)

( $\frac{1}{2}$ ) * (6) * (9) = (27)

Add up all of the values:

(35) + (45) + (35) + (27) + (27) = 169

How do you find out GCF (Greatest Common Factor) and LCM (Least Common Multiple)?

Mamont248 [21]

To find the GCF, first you must factor the 2 or more numbers. The GCF is the highest factor the numbers have in common. for example: you have 12 and 8. If you factor out the numbers for 12, you get
1,2,3,4,6,12
For 8, you get:
1,2,4,8
the GCF of this pair is 4 because it is the highest number that goes into both 8 and 12.
To find the LCM, you must find the first number that was multiplied and it must be the same. lets take 3 and 5. Multiply 3 by as many numbers you can think of. For now, lets just go up to 10.
3, 6, 9, 12 15, 18, 21, 24, 27, 30
now to the same for 5:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
in both 3 and 5, the first set of numbers that match in 30- therefore the LCM of 3 and 5 in 30. I hope this helps!
