Answer:

First picture - 20.42 m

Second picture - 12.9 m

Step-by-step explanation:

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

V=b^2\frac{h}3

Where,

b = base - 3.5 m

h = height - 5 m

Thus,

V=3.5^2\frac{5}{3}

20.41667m^3 ≈ 20.42m^3

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

V=b^2\frac{h}3

Where,

b = base - 3 m

h = height - 4.3 m

Thus,

V = 3^2\frac{4.3}{3}

12.9m^3
