Question

Use the following formula S=(lw)+S(lh)+S(wh) to find the surface area of a rectangular prism with the following dimensions -
Length = 1m
Width = 10m
Height = 5m

Answer 1

here is your solution

s = 2(lw)+2(wh)+2(hl) = 2(1×10)+2(10×5)+2(5×1) = 2(10)+2(50)+2(5) = 20+100+10 = 130 m²

hence, the surface area is 130 m².
