Answer 1

Divide your shape into two different shapes. a cube and a rectangular prism.

the cube has the measurements of 20*20*20 giving it a volume of 8000 inches^3

the rectangular prism has the measurements of 40*30*20 giving it a volume of 24000 inches^3

now add them together to get 32,000 inches^3 as your answer
