Question

The red line slices the cuboid horizontally from the centre as shown. The value which does not represent the perimeter of any face after slicing is

• A. 22 cm
• B. 14 cm
• C. 26 cm
• D. 20 cm

Answer 1

The correct option is C 26 cm

$\text{We know, perimeter of a}$
$\text{rectangle =}2\times (l+w)$

The 3 possible faces and the perimeter obtained on slicing the given cuboid horizontally along the red line are given below :

$\text{Face 1 : Perimeter =}2\times (7+4)=22cm$


$\text{Face 2 : Perimeter =}2\times (4+3)=14cm$


$\text{Face 3 : Perimeter =}2\times (7+3)=20cm$


So, the perimeter of a face after slicing can't be 26 cm.
