The surface area of the pyramid is 576.
<em>The square base is 144. It's just a square, so you multiply 12 (length) and 12 ( width) , which equals 144. </em>
<em>Then you find the area of one of the triangles. The equation to find triangles goes like this: 0.5 x B (base: 12) x H (height: 18). That would be 6 x 18 which is 108.</em>
<em>Since you got the area of 1 triangle and there are 4 triangles you have to multiply 108 by 4. That'll give you 432.</em>
<em>SO since you have the area of all the triangles and the square base the last thing you have to do is just add it all up. </em>
<em>The area of the triangles plus the area of the square base = the surface area.</em>

Answer:
Their trip is 50 mile long.
Step-by-step explanation:
I first divided 70 by 35 to get two.The two represents 1 mile = 2%. So then I subtracted 70 from 100 to get 30 then I divided 30 by 2 to get 15. Then I added 15 to the original 35 to get 50 miles for their 100%/destination of their trip. Hope this helps! Have a great day!
