You need to find what numbers can multiply to make that number. I hope this makes sense

To find the GCF of two numbers, list all the factors of those numbers, then underline all the matching factors, and finally find the grates common factor.

Example:

GCF (30, 25) = <em>x</em>

30: <u>1</u>,2,3,<u>5</u>,6,10,15,30

25: <u>1</u>,<u>5</u>,25

Common Factors: 1, 5

Greatest Common Factor: 5

<em>x</em>=5

GCF (30,25)=5

Answer:

Step-by-step explanation:

9 times 6 times 17 = volume

918 - volume

surface area= 2( length times width plus length times height plus height times width )

So just substitute the values and you get 618 cm squared

1.) To find the surface area, we want to find the area of each side, then add them all up together:
Area of base=lwA=(5)(5)A=25 cm²
Area of triangle=1/2bhA=(1/2)(5)(12.5)A=31.25 cm²
Since the 4 triangles have the same area, we can multiply the area we found by 4 and then add the area of the square:
SA=(4)(31.25) + 25SA=125+25SA=150 cm²

2.) <span>To find the volume use the formula: 

V=(1/3)lwh
V=(1/3)(5)(5)(12.5)
V=104.167 cm^3</span>
