Answer:

V_a=125 cubic\ inches

Step-by-step explanation:

From the question we are told that:

Height of pyramid A h_a=6

Height of pyramid B h_b=6

The volume of pyramid B  V_b= 312.5 cubic inches.

 

Generally the equation for volume for pyramid A is mathematically given by

Since they are similar

 \frac{l_a}{l_b}=\frac{V_a}{V_b}\\\\\frac{6}{15}=\frac{V_a}{312.5}\\\\V_a=\frac{6}{15}*312.5

 V_a=125 cubic\ inches
