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. 85,000cm3

B. 80,000cm3

C. 82,125cm3

D. 84,000cm3

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 = 384000cm3


And the inner volume = 115 × 75 × 35 = 301875cm3


Volume of the wood = outer-inner volume


= 384000-301875 = 82125cm3
