The base of this prism is triangle.

Step-by-step explanation:

Remark

It's a right angle triangle. I feel for 17 points, I should be telling you more.

Surface Area

The two faces are triangles. Their area = 1.5 * 2 / 2= 1.5

What I have you is the area of 1 triangle. There are 2 so 2*2.5 = 3

The height of the prism = 10 meters.

The Area of that face = L * w = 10 * 2.5

Area of that face = 25 m^2

Area of the rectangle containing 1.5 as the width = 1.5 * 10 = 15

Area of the rectangle containing 2 as the width = 2  * 10 = 20

The Total Surface Area = 20 + 15 + 25 + 5 = 65 m^2

Volume

Volume = Area of 1 triangle * height

Volume = 1.5 * 10 = 15 m^3

The base of this pyramid is an equilateral triangle.
