Answer:
144 cm²
Explanation:
1.) Find the area of all of the faces
10*4=40 (Top Face)
4*8=32 (Bottom Face)
6*8*0.5=24 (One Triangle)
6*8*.5=24 (Other Triangle)
6*4=24 (Back Face)
2.) Add them all together to get the surface area
40+32+24+24+24= 144
***Don't forget the cm². Some teachers are really annoying about this
