Answer: 18 square ft.
Step-by-step explanation:
Surface area is length*width. 1*1= 1*6= 6
since there are three cubes, it is 6*3= 18 square ft total.
Answer: The greatest depth of the Southern Ocean is 7.24
Step-by-step explanation:
So, if you add all the greatest depths up, you get 33.23
(33.23 + x)/5 = 8.094
Multiply each side by 5
33.23 + x = 40.47
Subtract 33.23 from each side
x = 7.24
You can check this by adding all the numbers up and dividing them by 5
40.47/5 = 8.094
