A rectangular prism that measures 8.2cm 5cm and 2cm has a volume of 82cm3
200
270 cubic inches
A rectangular prism is defined by three linear measures. Only 2 are given in the question.
Because the volume of a rectangular prism is the product of its length, width, and height, if these linear measures are doubled, the volume will increase by a factor of 23 = 8.
That task can be accomplished with a ruler, a tape measure, or a measuring cup.
Dimensions are linear measures whereas the volume is a cubic measure.
There is not an instrument designed to measure the volume of a rectangular box. You would use a ruler or tape measure or similar to measure its linear dimensions and a brain to multiply them together.
Volume is a 3-dimensional concept and cannot be determined from only 2 linear measures.
8*35*12=3360mm cubed
A ruler to find the measures of the edges and a brain to multiply them together.
A rectangle is a 2-dimensional object and cannot have a volume. A [rectangular] cuboid, of dimensions 8*12*24 has a volume = 2304 cubic units.
