Awater tank is in the shape of a right rectangular prism. its dimensions are 6 feet by 4 feet by 7 feet. what is the surface area of this tank?
a. 110 ft 2
b. 125 ft 2
c. 144 ft 2
d. 188 ft 2

In order to find surface area, you must add up all the area of the sides. On a rectangular prism, there are six sides. However, there are three pairs of identical sides. The sides are: 6x4, 6x7, and 4x7. So you must add them up: 24+42+28=?. Then you must multiply it by two: ? x 2. Then you have the answer.

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
