Volume of prism = Area of cross-section × height

Volume of blue prism = ([tex]4 \frac{1}{8} [/tex])×([tex]h_B[/tex]

Volume of red prism  = [tex]( \frac{1}{2})(4 \frac{1}{8}) [/tex]×[tex](h_R)[/tex]

[tex]V_{blue}:V_{red} [/tex]
[tex](4 \frac{1}{8})(h_B):( \frac{33}{16})(h_R) [/tex]
[tex] \frac{33}{8}h_B: \frac{33}{16}h_R [/tex]
[tex] \frac{66}{16}h_B: \frac{33}{16}h_R [/tex]
[tex]66h_B:33h_R[/tex]
[tex]66h_B = 33h_R[/tex]
[tex] \frac{66}{33}= \frac{h_R}{h_B} [/tex]
[tex] \frac{2}{1}= \frac{h_R}{h_B} [/tex] 
[tex]2:1=h_R:h_B[/tex]

The height of red prism is twice the height of the blue prism

Correct option: B
