Question

Johannas is building a square sandbox with sides 3 feet long. He wants to put sand 1.05 feet deep in the box. How many cubic feet of sand should Johannas order?

Answer 1

We make the drawing

now we can use the formula of the volume of a prism

`V=l* w* h`

where l is the length, w the width and h the height

then replacing

`\begin{gathered} V=3*3*1.05 \\ V=9.45 \end{gathered}`

Johannas should order 9.45 cubic feet of sand
