A covered wooden box has the inner

The correct answer is option (c) 82,125 cm3

Explanation:

The thickness of the wooden box is 2.5 cm

Then the outer measure of the wooden box be 115+5, 75+5, 35+5

Thus, the outer volume be = (120)(80)(40)

Outer volume = 384000 cm3

Given that, the inner volume = (115)(80)(40)

Inner volume = 301875 cm3

Hence, the volume of a wood = Outer volume – Inner volume

V = 384000 – 301875 cm3

V= 82125 cm3
