# A covered wooden box has the inner measures as 115cm, 75cm, and 35cm and thickness of wood as 2.5cm. The volume of the wood is

A. 85,000cm^{3}

B. 80,000cm^{3}

C. 82,125cm^{3}

D. 84,000cm^{3}

Answer :

Since , thickness of the box is 2.5cm,then outer measures will be 115 + 5,75 + 5 and 35 + 5,i.e.120cm,80cm and 40cm

The outer volume = 120 × 80 × 40 = 384000cm^{3}

And the inner volume = 115 × 75 × 35 = 301875cm^{3}

Volume of the wood = outer-inner volume

= 384000-301875 = 82125cm^{3}
