Step-by-step explanation:
Let P represent the length of the prism (11 in)
Let h represent the height of the prism (3 in)
Let B represent the breadth of the prism (4 in)
We have total surface area of prism
= 2(Ph + hB + PB)
= 2[(11in)(3in) + (3in)(4in) + (11in)(3in)]
= 178in².
Hence we have 178 square inches as the surface area.
