In a right rectangles pyramid with base edges a= 18 cm and b= 10 cm the slant height toward a is k= 13 cm while the slant height towards b is l= 15 cm. What is the surface area of the pyramid
To find the surface area of this pier amid, you will find the area of the base and the areas of all for triangular lateral faces. Add these together for the total surface area in the end.
Base : 18 x 10 = 180 cm²
1st set of lateral faces:
A = 1/2 x b x h 1/2 x 13 x 18 A = 117 cm² x 2 234 cm²
