Ask yourself: What times 3 equals my number?
As you can see 1x3=3 then 2x3=6, 3x3=9, and lastly 5x3=15
This is how you solve the chart.
Here you go!
I used the long division method,
The triangle <span>pyramid</span> is made up of 4 triangles.
------------------------------------
Formula:
------------------------------------
Area of triangle = 1/2 x base x height
------------------------------------
Area of the bottom triangle:
------------------------------------
Area = 1/2 x 9 x 7.8
Area = 35.1 yd²
------------------------------------
Area of the 3 side triangles:
------------------------------------
Area = 3 [ 1/2 x 9 x 10 ]
Area = 135 yd²
------------------------------------
Total Area:
------------------------------------
Total Area = 135 + 35.1
Total Area = 170.1 yd²
------------------------------------------------------------------------
Answer: Surface Area = 170.1 yd².
------------------------------------------------------------------------
