Question

Find the total surface area of a whole wheat measured 20m into 18 metres into 3 metres

Answer 1

Total surface area of whole wheat is given by= 2 ×[LB+BH+HL], where

L=Length

B=Breadth

H=Height

So, T.S.A= 2× [20×18+18×3+20 ×3]

               = 2 × [360 +54+60]

               = 2 × [474]

               = 948 m³
