Answer:

1395

Explanation:

SA is the sum of all areas.

THe area of each side of the cube is 15^2 feet = 225 feet

There are 5 outwards facing sides of the cube so 225*5=1125

Each side of the triangle has an area of 1/2 *b*h, in this case, 1/2*15*9=67.5

THe triangle has four sides so 67.5*4=270

270+1125=1395
