Answer:
408 sq. in.
Step-by-step explanation:
The total surface area of the pyramid is the sum of all 4 faces (each of them a triangle) and square base.
Triangle area is
where b is base and h is height.
base of triangle is 12 and height is 11
So area of each triangle is ![\frac{1}{2}(12)(11)=66](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2812%29%2811%29%3D66)
There are 4 of them, so total is 66 * 4 = 264
Now, square has an area of
where s is the side length.
It is given s = 12, so the area of the square base is:
![(12)^2=144](https://tex.z-dn.net/?f=%2812%29%5E2%3D144)
Total Surface Area of the Pyramid is 264 + 144 = 408 sq. in.
To find the unit rate you do distance ÷ time
16 miles ÷ 2 hours = 18
To find the time you do distance ÷ unit rate
20 miles ÷ 18 = 1.1
To find the distance you do time • unit rate
3 hours • 18 = 54
2) 1.1, 54, 1.8, 90, 27
3) 48, 3, 30, 2, 1
