Answer 1

The beach toy item is a square based pyramid with the following parameters

`\begin{gathered} side\text{ length of base= 4 inches} \\ height\text{ of pyramid = 4 inches } \end{gathered}`

Step-by-step explanation

The volume of the pyramid will indicate the volume of sand that the beach item can contain.

`volume=(1)/(3)* base\text{ area}* height`

Therefore, we will have;

`\begin{gathered} volume=(1)/(3)*4*4*4 \\ =(1)/(3)*64=21.3 \end{gathered}`
