Question

The capacity of a closed wooden box of thickness 1 cm and of dimensions $32cm\times 20cm\times 17cm$, is

• A. $10880c{m}^3$
• B. $69c{m}^3$
• C. $8100c{m}^3$
• D. $8000c{m}^3$

Answer 1

The correct option is C $8100c{m}^3$

Given that the thickness $=1cm$

Therefore,

The length of inner box $=32-2=30cm$

The breath of inner box $=20-2=18cm$

The height of inner box $=17-2=15cm$

Therefore, the dimensions of inner box are

$l=30cm,b=18cm,h=15cm$

Volume of inner box $=l\times b\times h$

$=30\times 18\times 15$

$=8100c{m}^3$

Hence, this is the answer.
