The area of the shaded base of the triangular prism is 115 s

The area of the shaded base of the triangular prism is 11.5 square meters. What is the total surface area of the prism? F. 177.38 m^2 G. 201.3 m^2 H. 1505.4 m^2 J. 124.11 m^2

Solution

Total Surface area (SA) will be

= 2*SA of triangular shade + SA of Base + SA of outside rectangular field + SA of inside rectangular field

= 2*11.5 + 9.3*4.6 + 6.9*9.3 + 5.1*9.3

= 177.38 m^2

Correct option is F.
