If the two prisms are stacked on top of each other then the height of the prism is 30 inches. Then the volume of the prism will be 1080 in³.
What is a rectangular prism?
A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.
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.
One prism is 10 inches tall and the other is twice as tall.
The two prisms are stacked on top of each other.
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
