A right rectangular prism measures 5 m by 4 m by 3 m. A new solid is created by placing the entire 4 m by 3 m side of the prism against one side of another right rectangular prism measuring 4 m by 5 m by 6 m.

What is the surface area of the new solid?

Answer 1

2(5*4)+2(4*3)+2(3*5)=94 sq.m (Orginial SA)
2(4*5)+2(5*6)+2(6*4)=148 sq.m (Total SA)

148-94=54 (New SA)
