Answer:
<h2>S.A. = 60 in²</h2>
Step-by-step explanation:
We have 4 congruent triangles.
The formula of an area of a triangle:
![A_\triangle=\dfrac{1}{2}bh](https://tex.z-dn.net/?f=A_%5Ctriangle%3D%5Cdfrac%7B1%7D%7B2%7Dbh)
b - base
h - height
We have b = 5in and h = 6in. Substitute:
![A_\triangle=\dfrac{1}{2}(5)(6)=(5)(3)=15\ in^2](https://tex.z-dn.net/?f=A_%5Ctriangle%3D%5Cdfrac%7B1%7D%7B2%7D%285%29%286%29%3D%285%29%283%29%3D15%5C%20in%5E2)
The Surface Area of the triangular pyramid:
![S.A.=4\cdot15\ in^2=60\ in^2](https://tex.z-dn.net/?f=S.A.%3D4%5Ccdot15%5C%20in%5E2%3D60%5C%20in%5E2)
Answer:
275 km
Step-by-step explanation:
It has 1 - 3/8 = 5/8 of a tank left.
3/8 of a gallon gives 165 km
So 1 gallon gives 165 / 3/8 = 165 * 8/3 km
5/8 gallon gives 168 * 8/3 * 5/8 km
= 165 * 5/3
= 275 km (answer)
