This is a picture of a cube and the net for this cube. plz asap
what is the surface area of this cube?

90 mm²

225 mm²

450 mm²

1350 mm²

Option D. 1350 mm² is the answer.

Step-by-step explanation:

In the given picture the cubes are arranged in a way that only 6 faces of the cubes are visible. Each side of the cubes are 15 mm.

So area of the each face of a cube = 15×15 = 225 mm²

Since there are 6 faces visible so total area of the picture = 6×225 = 1350 mm²

Option D. 1350 mm² is the answer.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
