Question

A closed wooden box 80 cm long, 65 cm wide and 45 cm high, is made of 2.5-

cm-thick wood. Find the capacity of the box and its weight if 100 cm3 of wood weighs 8 g.​

Answer 1

ANSWER

l =80−2(2.5)=75cm

b =60cm

h =40cm

[Dimensions of inside of box]

v=l ′ b ′h ′=(75)(60)(40)

=180000cm²

100cm³ →8g

180000cm³ → 8/100×180000

=14400g

Weight=14.4 kg.
