The volume of the blue-outlines prism
Answer:
70 m^2.
Step-by-step explanation:
Area of the triangle = 1/2 * base * height.
Counting the squares on the coordinate plane:
Base = 7, height = 5
Each square = 2 meters
So the area = 1/2 * 14 * 10
= 70m
The volume is around 50.27
the surface area is: 75.4
the perimeter 25.13
