In a rectangular prism, surface area is calculated by multiply all the faces of the prism that you can touch

Becuase there's four faces that have the measurement of 5*3, you do 4(5*3) and because there's only two faces that have the measurement of 3*3, you do 2(3*3)

Which becomes 4(5*3)+2(3*3) which is 78
