Solid A and solid B are cuboids in a set of storage-container models

Solid A: length 7 cm, width 22 cm, height 23 cm. Solid B: length 14 cm, width 44 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.

Are solid A and solid B similar? Select the verdict with the complete ratio reason

(b)1 mark

Using the corresponding width, calculate the proposed linear scale factor \(k\) from solid A to solid B

Format: Exact number or fraction
(c)1 mark

If every dimension followed the proposed \(k\), calculate the volume factor \(k^3\)
