Question

The dimensions of open box is 50cm 40 cm 23 cm its thickness is 2 cm if 1 cubic cm wieght is o.5 gms find the wieght of box?

Answer 1

Answer:

Step-by-step explanation:

Given,

Outer dimensions of the box = 50 cm, 40 cm and 23 cm

Outer volume of the box = 50 × 40 × 23 = 46000 cu cm

Inner dimensions of the box:

Length = (50 - 2×3) = 44 cm

Breadth = (40 - 2×3) = 34 cm

Height = (23 - 30 = 20 cm

Inner volume of the box = 44 × 34 × 20 = 29920 cu cm

Volume of the wood = Outer Volume - Inner Volume = 46000 - 29920 =

16080 cu cm

Weight of the wood per cu cm = 0.5 g

Weight of the wood used for making the box = 16080 × 0.5 = 8040 g = 8.04 kg.
