Answer:336.0 square inches
Explanation:
Given that the base b=8 inches in this case S1 and the base is the same. The height of the triangle h is 6 inches, the length of the prism is 12 inches and the hypotenuse of the right triangle =10 inches
The surface area of the right triangular prism is given by the formula
=bh+(S1+S2+h)L
On substituting the values , we get
SA=8 x6+(8+10+6) *12
SA=48+(24)*12
SA=48+288
SA=336.0 squareinches
