Answer:  

Total Surface Area of the given regular pyramid = 153 units²

Step-by-step explanation:

Base length of the regular pyramid, l  = 9 units

Base width of the regular pyramid, w = 9 units

Height of the regular pyramid, h = 7 units

Perimeter of base = 3 × 9

                              = 27 units

\text{Area of base = }\frac{1}{\times Base\times Height\\\\Area = \frac{1}{2}\times 9\times 7=21.5\:\:units^2

\text{Now, Total Surface Area = }\frac{1}{2}\times p\times l+A\\\\\implies\text{Total Surface Area = }\frac{1}{2}\times 27\times 9+31.5

Hence, Total Surface Area of the given regular pyramid = 153 units²

If a snail crawls 12 centimeters per hour, how long will it take for the snail to travel 1 meter
Pavlova-9 [17]

Answer: 8 1/3 hours or 500 minutes

Step-by-step explanation:

Keep in mind that there are 100 centimeters in a meter.

The snail moves at a pace of 12 cm/h, and needs to go 100 cm.  You can just divide 100/12 to get 8 1/3, which is how many hours (groups of 12 cm) it takes for the snail to travel 100 cm (1 meter).

If necessary, you can also multiply 8 1/3 by 60 to get the number of minutes the snail takes.  8 times 60 is 480, and 1/3 of an hour is 20, so add 480+20 to get 500 minutes.
