A toy store is building a display with two rectangular prisms.
The base of each prism is a square with an edge length of 6 inches.

Then the total volume of the display will be
The volume of the prism will be
Volume = Base area × Height
Then the height of the second prism will be
h₂ = 2 × 10 = 20 inches
Then the volume of the prism will be
Volume = 6 × 6 × 10 + 6 × 6 × 20
Volume = 360 + 720
Volume = 1080 cubic inches
