Question

Work out the surface area of the prism.​

Answer 1

Answer:

Step-by-step explanation:

We can find the surface area by multiplying 20⋅6 twice, multiplying 6⋅12 twice, and multiplying 20⋅16 twice. Adding these up, we get:

SA = 2(20)(6) + 2(6)(12) + 2(20)(16)

SA = 240 + 144 + 640

SA = 880 + 144

SA = 1024

Solution: 1024 centimeters squared
