Question 147083: If a figure has 7m x 3m and the base for this solid is 8m high. What would the calculation be for the surface area of this solid. Answer by psbhowmick(878) (Show Source):
You can put this solution on YOUR website! It is a right angled prism with rectangular base.
Total surface area = Sum of area of all 6 faces
The opposite faces of a rectangular prism are identical so it leaves to find the area of 3 non-opposite faces of the prism.
Total surface area = 2 x (Sum of area of all 3 non-opposite to each other faces)
Total surface area = 2 x (7x3 + 3x8 + 8x7) = 2 x (21 + 24 + 56) = 202 sq m
