Answer:

[tex]H_B=169.2m[/tex]

Step-by-step explanation:

From the question we are told that:

Average height of blocks [tex]H_{ABC}=145.6[/tex]

Height of block A [tex]H_A=128.7[/tex]

Height of block C [tex]H_C=138.9[/tex]

Generally the equation for Height of block C is mathematically given by

Since

[tex]H_{ABC}=\frac{H_A+H_B+H_C}{3}[/tex]

Therefore

[tex]H_B=(H_{ABC}*3)-(H_A+H_B)[/tex]

[tex]H_B=(145.6*3)-(128.7+138.9)[/tex]

[tex]H_B=169.2m[/tex]
