Question

• A. $6$ cm $\times$ $6$ cm $\times$ $6$ cm
• B. $12$ cm $\times$ $12$ cm $\times$ $12$ cm
• C. $9$ cm $\times$ $6$ cm $\times$ $3$ cm
• D. $6$ cm $\times$ $3$ cm $\times$ $3$ cm

Answer 1

Answer: (D)

$6$ cm $\times$ $3$ cm $\times$ $3$ cm

Dimensions of cube are $length\times breadth\times height$

When two cubes are placed together the base that is the $breadth$ doubles rest all remains the same hence the dimensions becomes $6cm\times 3cm\times 3cm$
