Answer:

Step-by-step explanation:
Surface area is the sum of all sides of the area. Since it is a rectangular prism, each surface area will be multiplied by two to account for the opposite side (ex. top and bottom are the same area).
The front/back area is
or 11. So the sum of the areas is 22.
The right/left area is
or 2. So the sum of the areas is 4.
The top/bottom area is
or 22. So the sum of the areas if 44.
We add these together to find the surface area.

The surface area is 
Answer:

Answer:
a) 18 grapefruits
b) 6 grapefruits
Step-by-step explanation:
a) n = 14.4 / 0.80 = 18 grapefruits
b) n = (14.4 / 3) / 0.8 = 6 grapefruits
12 songs. 25% of 12 is 3, so you add 3 to 12 and get 15. You then find that 20% of 15 is 3 so you subtract 3 from 15 and get 12 again.
