Volume of the Triangular prism = 1/2 (base*height*length)
V = 1/2 (2 * 2 * 5)
V = 10 cubic inches.
For the surface area, you can divide the prism into parts:
It's made of three rectangles and two equal triangles.
For the two triangles:
The area of each of the triangles is 1/2(base x height)
Area of each triangles = 1/2 (2 * 5)
Area of each triangles = 5 inches^2.
For the three rectangles:
* one is equal to base x length,
Rectangle1 = 2 x 5
Rectangle1 = 10 inches^2.
* another is equal to side 1 x length
Rectangle2 = 3 x 5
Rectangle2 = 15 inches^2
* and the last is equal to side 2 x length.
Rectangle3 = 3 x 5
Rectangle3 = 15 inches^2
Adding all the components up,
10 + 15 + 15 + 5 + 5 = 50 inches^2
Therefore, the surface area of the prism is greater than volume 50 > 10
hpe this helps:)
