If 1 cubic cm of metal used in the box weighs 0.5 gms, find the weight of the box.

Answer 1

Answer:

5612 grams/5.612 kg

Step-by-step explanation:

Volume of whole cuboid= 50x40x23=46000cubic.cm

for empty space remaining, subtract 4cm (2cm each side)

L=46 B=36 H=21 (since it is an open box)

Volume of empty space= 46x36x21= 34776cubic.cm

Therefore volume of the physical box= 46000-34776=11224cubic.cm

If 1 cubic cm weighs 0.5 grams,

then 11224 cubic cm weighs= 11224x0.5=5612 grams

The box weighs 5612 grams or 5.612 kgs
