Answer: 216 in

Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.

Cuboid's volume is l · w · h

the surface area is just the area of all the shapes added together, i didn't see any lateral surface area on there, so im not gonna explain unless you want me to.
