barxatty [35]
He weighs 196 lbs and 6 ounces. if you add the pounds (180 to 3, 5, 6)you get 194. then you add he ounces, and remember that there are 16 ounces in a pound and 8 ounces in a cup, (6 to 9, 12, 11) you get 2lbs and 6 ounces. then you add the 2 extra pounds to the 194 and you get, all together, 196 lbs and 6 ounces.

Find the volume of the square pyramid. Round to the nearest tenth.
gregori [183]

Answer:

363.6

Step-by-step explanation:

Given in the question,

side of square = 10

Step 1

To find the slant height pyramid we will use pythagorus theorem

13² = 5² + height²

height = √13² - 5²

           = 12

Now find the height of the pyramid

12² = 5² + height²

height = 10.91

Step 2

Base area of the pyramid

area = l²

       = 10²

       = 100

Step 3

Volume = 1/3(height)(basearea)

             = 1/3(10.91)(100)

             = 363.6
