4) If Mrs. Rodriguez’s trays makes ice cubes that are each 1 cubic inch, how many cubes can be made with five trays?

The question requires that we determine the volume of the cube
The volume of a cube is given by
[tex]V=\text{Lenght}\times Breadth\times Depth[/tex]The volume of 1 tray is obtained as follow
[tex]V=1\times1\times1=1\text{ cubic inch}[/tex]Then 5 trays will make
[tex]5\times1\text{ cubic inch=5 cubic inches}[/tex]Thus, 5 cubic inches of ice can be made with 5 trays
