I need to find the surface area of this
2 answers:
We need to find surface area, so we can imagine breaking it up into face net. There will be 18 × 18 square base, four 18 × 40 rectangles, and four triangles with base 18 and height 13. So the surface area would be sum of these areas. That would be 18×18 + 4( 18 × 40 ) + 4( (1/2) 18×13 ) = <span>3672 Final answer: 3672 m </span>² Hope this helps.
The surfaces area for the rectangular prism is 3528 meters squared, the surface area of the rectangular pyramid is 144 meters squared. add these together to get 3,672 meters squared
