We know that
[surface area of the pyramid]=area of the base+4*[area of one lateral triangle]
area of the base=14*14------> 196 cm²
area of one lateral triangle=b*h/2
b is the length side of the square
b=14 cm
h is the slant height
h=15 cm
area of one lateral triangle=14*15/2-----> 105 cm²
[surface area of the pyramid]=196 cm²+4*[105 cm²]-----> 616 cm²
the answer is
616 cm²
Let us first convert 10 minutes 12 seconds in seconds.
So
10 minutes 12 seconds = (10 * 60 ) + 12 seconds
= 600 + 12 seconds
= 612 seconds
Now
Let us convert the 612 seconds into minutes
612 seconds = 612/60 minutes
= 10.20 minutes
Now
The distance covered by Marnie in 10.2 minutes = 1 mile
hen
Distance covered by Marnie in 60 minutes = (60/10.2) miles
= 5.88 miles
Then the unit rate will be 5.88 miles per hour
