Rosario draws the right triangular prism shown here and calculates the volume. She then draws a second right triangular prism in which the dimensions are tripled. What is the relationship between the volumes of the two prisms?
Question
Answer:
The volume of the original prism is given by:V1 = (1/2) * (b) * (h) * (H)
Where,
b: base of the triangle
h: height of the triangle
H: prism height
The volume of the prism with new dimensions is:
V2 = (1/2) * (3b) * (3h) * (3H)
Rewriting:
V2 = (3 * 3 * 3) * (1/2) * (b) * (h) * (H)
V2 = (27) * (1/2) * (b) * (h) * (H)
V2 = (27) * V1
Answer:
The relationship between the volumes of the two prisms is:
V2 = (27) * V1
