Surface Area you get by getting the area of each of the 2 dimensional shapes, the formula to get the surface area for a rectangualr prism is 2(wl+hl+hw), so you would plug in 2((5(6))+((4(6))+(4(5)) which will give you 2((30)+(24)+(20)) which will then give you 2(74) and the final answer will be 148 cm^2
The formula for Surface Area is w(l)(h) so in this case it will be 5(6)(4) which will be 30(4)= 120 cm^3
