to find the surface area, you need to find the area of all 6 sides using the dimensions given. each visible side has an opposite side that has the same dimensions.

1) 6*2=12

2) 6*2=12

3) 9*2=18

4) 9*2=18

5) 9*6=54

6) 9*6=54

then, you have to add all 6 sides together.

12+12+18+18+54+54

24+36+108

60+108

<u>168 cm squared is the surface area</u>

A bag contains 5 blue marbles, 2 black marbles, and 3 red marbles. A marble is randomly drawn from the bag.

Delvig [45]

Since you are not allowed to draw a black marble, then you have only 7 ways to draw either a blue or a red marble. The sum of all marbles is 10. So the probability of not drawing a black marble is 7/10 and the probability of drawing a red marble is 2/10 or 1/5.
