Answer:
The surface area is 31.75 inches
Step-by-step explanation:
To find the area of a triangle, we use the formula
, or base · height ÷ 2
Using this formula, we find that the area of the front and back triangles is 10
On the side triangles, the formula shows the area to be 6.75
The base, which has a width of 5 and a length of 3, is 15
Add the numbers together and you get a total surface area of 31.75 inches
