Question

A closed box is made of wood which is 1.8 cm thick. Its externa
dimensions are 84 cm x 64 cm x 50 cm. Find:
(i) the capacity of the box.
ii) the volume of the wood used in making the box.
ii) the weight of the empty box iflcm' of wood weighs 6.8 g.​

Answer 1

Answer:

the volume of wood used in making box = 2(lb+bh+hl)

Step-by-step explanation:

l=84cm

b=64cm

h=50cm

2(lb+bh+hl)

2[(84×64)+(64×50)+(50×84)]

2(5376+3200+4200)

2(8576+4200)

2(12776)

25552

the weight of the empty box of wood = 68/10 × 25552

= 17353.6

Hence the weight of the empty box of wood = 17353.6
