Given,
The height of the shape is 18 inches.
The height of cuboidal part is 11 inches.
The height of pyramid part is 18- 11 = 7 inches.
The side of the cuboidal part is 3 inches.
The base of the pyramid part is also 3 inches.
The volume of the cuboidal part is,
[tex]\begin{gathered} \text{Volume =l}\times b\times h \\ \text{Volume =s}\times\text{s}\times h \\ \text{ =3}\times3\times11 \\ \text{ =}99inches^3^{} \end{gathered}[/tex]
The volume of pyramid part is,
[tex]\text{Volume =}a^2+2a\sqrt{\frac{a^2}{4}+h^2}[/tex]
Here, the value of a is 3 and h is 7 then,
