Find the surface area of a right triangle prism with legs measuring 3 and 4 and a height of 10. a. 130 b. 132 c. 144 d. 140

Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
 We have then:
 
 
 
 
 Then the surface area is given by the sum of the areas.
 Triangle of the base and the top:
 
 Rectangle 1:
 
 Rectangle 2:
 
 Rectangle 3:
 
 Finally, the surface area is:
 
 Substituting values:
 
 
 The surface area of a right triangle prism is:
 B. 132
