Answer:
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
