Solid A and solid B are cuboids in a set of packaging prototypes

Solid A: length 26 cm, width 18 cm, height 23 cm. Solid B: length 41 cm, width 36 cm, height 46 cm. Each measurement names the corresponding linear role shown

Solid A. Solid A and Solid B are cuboids. Corresponding dimensions are labelled. The panels use separate drawing scales; compare the measurements.lwhSolid ASolid B. Solid A and Solid B are cuboids.
