The dimension Garet must not use to construct the rectangular prism is 10 cm × 2 cm × 6 cm.
He is using 96 1cm cubes to build a rectangular prism . He wants the rectangular prism to have a height of 6 cm.
Volume of a cube?
volume of a cube = l³
where
Therefore, each volume of the cube is as follows:
volume of cube = 1³ = 1 cm³
The total volume of the whole 96 cubes = 96 cm³
Therefore, the volume of the rectangular prism should be the same with the volume of the whole cubes. But must have a height of 6cm.
Hence, the dimension that Garret must not use is 10 cm × 2 cm × 6 cm.
