Mathematics

3 0

Step-by-step explanation:

90 = 2 * 3² * 5

126 = 2 * 3² * 7

180 = 2² * 3² * 5

990 = 2 * 3² * 5 * 11

All of the numbers have 2 and 3² in their prime factorization. Therefore the GCF is 2 * 3² = 18.

Ok guys i need some help

Hello!

The surface area is the area of all of the shapes on the net added up. First we will find the area of the two triangles.

A=0.5bh
A=0.5(3·6)
A=0.5(18)
A=9

Since there are two triangles we double this area, giving us 18.

Now let's find the length of the two side rectangles.

7(4)=28
28+28=56

Now to find the middle rectangle.

6(7)=42

Now we add up all of the area to find the surface area.

42+56+18=116

The surface area is 116 cm².

I hope this helps!
